I manage an ophthalmology office in Florida. A new Zeiss cirrus Oct starts around 30k used for macula and retina scans. An auto refractor 15k for calculating your vision. The Humphrey visual field that we have is a lot larger then yours. They start around 30k and are used for glaucoma. That last machine you have is a surgical phaco for performing cataract surgery. The doctor uses that machine to put energy into your natural lens to break it up and suck out the little pieces. Then the doctor can implant a replacement lens. This machine is big bucks with a new one 100 to 200k. Awesome find Dave. Congrats
@@rkan2 In the USA not much. Maybe 1 to 2 grand each. No doctor in the USA would want to purchase 20 year old equipment. However they do resell these items in third world countries where they can’t afford new.
@@MelodicMurder the machines are from the Victorian College of Optometry. And listen to how Dave talks. He's in Australia. The college is now called the Australian College of Optometry. They do treat patients.
Hi Dave. Please exercise caution if powering these bits of kit during a teardown, as terms such as "coherence" and "frequency doubling" strongly indicate that there _may_ be lasers involved. If not lasers, some serious high-intensity sources that may be invisible, yet optically dangerous. Indeed "Frequency doubling" is the scariest term, as it indicates that a nonlinear crystal might be converting invisible IR to the visible spectrum, as is the case with frequency-doubled Nd:YAG lasers. It's not guaranteed, and I'm sure for your $100,000 there must be some serious safety interlocks, however better safe than blind. Source: I used to work in a holography lab.
@@adamreiss4548 You are likely correct. Out of interest, does it imply that oscillation increases or decreases visual acuity? Either way, if you see any of the "danger words", you should assume you are potentially entering in to a dangerous situation.
Dave - optometrist here. OCT does the front of the eye. All the ones in the last 15 years can do the back and front of the eye. This is unsellable as no one would be interested in buying it these days. Next is a matrix 715 field tester. It is useless without the printer. But I have seen them sold for about 2-3 grand with a keyboard. Someone on our Facebook classifieds had a keyboard for sale for $50. Possibly a good sale. The next is an autorefractor, it measures the glasses prescription and curvature. Once again very old and possibly unsellable. Finally a laser machine to change peoples prescriptions. But it needs certain disposable items which are no longer available. So overall, the matrix 715 is sellable. If you can find the right hp printer you might get 4-5000 for it. I have one at work so let me know if you want the model number.
USB to PS/2 adaptors only work for mouse which are designed to work with USB to PS/2 adaptors. The adaptors are completely passive and requires the electronics inside the mouse to detect that it is plugged into a PS/2 port and change their electrical protocol accordingly.
OCT optical coherence tomography, a high resolution imaging device used to look into the retina...kind of like a high resolution ultrasound but using light. In there you'd find a superflourescent laser, high speed detector and other wizardry.
Got blown away 6 months ago when I was at the hospital for a full eye/retinal examination.......whole suite of new machines. One that took my eye (pun intended) was a machine that took photos of my retina at various angles and then which constructed a 3D image of the retina. But not just the surface, it managed to image into the layers of the retina and which the consultant could peel back digitally!.............and update a problem I have which turns out had been misdiagnosed for 15 years. They originally thought I had RVO's (retinal vein occlusions) but it turns out they are CSR's (Central serous retinopathy) if I remember correctly.
Wow. I got some demos (using my own eye) of this sort of thing in a research lab several years back, so great that this tech is out there making a serious difference!
I like the fact that this really high tech kit is basically running a regular XP desktop. There was even a VNC server on there. I hope they never normally hook these to the internet lol.
I think they are on the internal network as I assume that the doctor somehow wants to collect the data from 4 different machines into one patient file. And the doctors officers also needs a hook up to the insurance system. And The doctors office also needs e-mail. Start to see where this leads?
Carl Zeiss is making the the best opticals for almost everything, They are main supplier to ASML, that build UEV lithography machine for wafers as low as 5 nm.
For those that are not from upstate NY: Skaneateles is pronounced Skinny-atlas. I went up there to consult with Welch Allyn on their IT for a few weeks and I learned it firsthand. :)
I love my Zeiss! Well, to be clear, I can only afford the little box of premoistened glasses wipes. Which they probably don't have hands on, just let the logo get printed on the packs, but still. They're pretty nice 😁 Sweet scores, by the way.
I'd have a look around the files stored in the OCT machine. Knowing how people typically use computers, I'd say there's a good chance that the password is just saved in a text file somewhere.
I find it quite interesting that the Visante OCT has what looks to be a normal HP USFF PC behind the side panel under the screen (I recognise the faceplate, laptop DVD drive and power button location) but then has the I/O shield of a regular PC on the back of it, maybe two whole PCs inside?? If that's the case, I'd guess they're using the XP PC as an interface, and the much newer HP machine as a data cruncher.
Where would they buy the disposables for the laser, let's say? If they are no longer in production it would be getting progressively harder to acquire them, and the price would likely go up.
OD and OS are right and left(OS The S is sinister), I know this from having a huge number of scans on both of my eyes as I suffer from Pellucid Margin Degeneration and have had my right eye collagen cross linked( basically the collagen is set rigid) and a full corneal graft in my left eye
I recently went to get a OCT scan of my eyes, the retina in my case, and it was more expensive than you payed for the whole device... It uses a laser to scan across the eye, so be careful when you switch it on disassembled.
A couple of years I had an OCT taken - the instrument was brand new here at the hospital and I was at least as much interested in the technique as the ophthalmist in my eye. The interesting thing is how the instrument can "see" even through the retina and show you the cross section just by shining light from the front into the eye.
I'm always surprised to see a full-on desktop version of an OS on an embedded device like this when an embedded version of the same OS, booting right into an app without any OS shell, would be more appropriate.
I've worked on this equipment for 15 years, I see a Humphrey matrix, and an OCT. There are multiple hardware variants for all the devices. Let me know if you want some help.
Nokia, Casio, Panasonic, Sharp use lenses made by Zeiss. German optics company. Being around for quite awhile, over 175 plus years. Great find! Now you can do your own optometry and get a great discount! 😂
Very nice haul. Best I recently got at auction was an ionscan 400B for about $30. Now I can test visitors for what they have been up to (-: Worked on turn on.
Great auction score Dave! I've seen this sort of thing happen a few times over the years where super expensive bits of test kit make their way into these situations very interesting.
So, you hauled some cool stuff from there after all? Nice. Victorian School of Optometry? Sounds pretty antiquated. It's been at least twelve decades now! :D Zeiss does all kinds of high-quality optics both for consumer and professional markets. Camera lenses, spectrometers, whatnot. By the way, I've got a 1980s vintage Spekol 11 spectrophotometer in my lab; still gotta fire it up. I used to do some experiments with that stuff back when I was studying. Wonder if you could run some old flight simulator on Nvision (not NVidia; BTW their open-source driver release was hot damn shocking!). Cooler than Doom! (not that I dislike Doom, but it's so all over the place that we really should try something different)
Last one is for LASIK surgery, likely tossed because the consumables are now classed as obsolete, and thus expensive, and not available from the manufacturer any more. Needs to have the right fluids supplied, which it variously heats, cools and pumps around, so as to cool the ablation wand, and flush the lenses clear, plus wash the burnt off corneal tissue away while you are busy carving off the surface of the cornea and lens to correct vision. Just remember with LASIK you only really get one or two chances at most, and every time there is the danger to go too far and make the problem worse. Inside will be a Xenon light source and a ruby laser, that is pulsed to provide the energy pulses that are used to variously ablate the cornea and lens to shape, or which is used via another tool head to focus on the rear of the eye, so the surgeon can pass a deeply focussed pulse into the eye, to spot weld the detached retina back onto the rear of the eye. You often are awake for this, just clamped into a head frame and immobile, and with your eyes dilated, and blocked from moving, with a drug remarkably similar to terodotoxin, like in Fugu pufferfish. Yes also had fun with my optometrist, with him trying all the new toys at the practise he was doing a locum at for a few months, because he also wanted to play with them, with a willing participant. CT scan of the eye does take a half hour per side, delivering a result accurate to 0.05mm on all dimensions, and the automatic tester he tried agreed to within 0.1 of his manual eye test, and with 15 years of my tests by him to hand, and it being stable, he was very happy with that. Just that that was over $2 million in the one suite though..... Excluding the regular optometrist toolset and chairs, just the 2 scanners and the vision testers.
actually no, LASIK is done by some pretty heavy lasers. That last thing is for vitrectomy surgeries (posterior segment of the eye). Although it can to cataracts, but it really sucks at doing those. Been End of Life for close to 10 years now.
Catweazle, visiting Dave’s lab: “Ah, this is where the Master makes his Electrickity! All gears for Electrickity has wires, and all this has wires!” (Catweazle pulls hard at probes from delicate oscilloscope)
Zeiss make stuff like that to this day, i have been unfortunate enough to have to deal with there software from the IT side of things. They are good bits of kit but like anything the software is so focused on the medical side of things they forget humans have to use it and things like security are a thing. The Zeiss service password is Usually Zeiss or Service and the year the company was founded or Carl Zeiss birthday .
I would see if you could find some place to donate them so they go to a less developed country where they can be used. I would assume there's a market for deprecated medical equipment in developing nations.
Can't wait for the electromechanical nudity. I have a suspicion that a reason for there demise is unable to upgrade of fix units due to old software. Even as far as not being able to get things that will plug into older sockets.
I see, you got some of your former optometrist equipment? Last time I went to the optometrist I had to look thru the lenses, one eye at a time, a few puffs of air and I got my prescription. I'm sure you got a deal on this stuff and I'm sure that equipment would have to be calibrated (hopefully) from time to time. Looks interesting. First initial reactions: " two minute teardown" and "Don't turn it on, take it apart", and "warranty void if not removed". Looking forward to the teardowns.
Zeiss made the optics for each equipment, the rest of each equipment as indicated. Carl Zeiss is #2 to Leica in the desktop Microscope world. Zeiss does more medical parts than Leica. Ron W4BIN
Based on what MelodicMurder said above, I perhaps misremembered the price. I won't be back there until December. The one they use on me that looks like that takes photos of the back of my eye. I've had several tests where they inject Fluroscine into my vein and then take photos of the back of my eye as quickly as they can to test how fast it spreads to eye, and if it's leaking anywhere.
latest ones probably just have wifi ;) oh, and online licenses, these old ones might be worth a pretty penny in the future once all the 'clouds' precipitate.
Cool! I had lasik surgery years before and my eyesight got worse from then and my doctor said I can do a top up and get closer to zero/zero. Let me know if you need a pair of eyeballs to test your new lasers device 😂
Imagine a JohnWick sequel where in the protagonist is on a mission in Australia and is need of an electronics engineer and optometrist combo for a sniper action attack, visits Dave in a dungeon, where Dave offers his service for that gold coin. How cool is that ?!
You may be able to make a few bucks on the side doing some laser corrective eye surgery. Pay full price for one eyeball, and get the other eyeball at half off. You will have to beat the crowds away!
PS/2 Mice and KB are not connected/disconnected with power on as theuy sre inyerupt driben and a habg or crash or damage can occur. USB allows this but has a delay in responce vs PS/2.
I have just last week wreaked a going Retinal Camera, similar vintage that I picked up from the wreakers, its the second one they have had so I suspect they are just not current and no body wants them, why else would they send them to a wreaker if there was any market for them. Nicely made but very little that I could find to reuse. I kept the PSU as its linear and a good range of voltages, and a couple of nice electromechanically stuff but honestly the rest is pretty useless. Shame to wreak this but its what happens these days Im afraid.
