What you have there is a very rare and valuable polarizing and petrological outfit. If you were to build a very careful auction with lots of good pictures you would probably be amazed at what it might bring on ebay. I think prices may be a bit lower as the people who recognize these things die off b...

This type of optic are often used on FTIR and Raman spectrographs. The imaging performance may not be the parameter that they optimized.

The camera adapter that Scarodactyl posted will work with an M4xx series but not with this one. As you have noted it takes a 30 mm eyepiece. 30 mm camera adapters are easily available and should work well. I would suggest a smaller sensor camera to use with this scope. These scopes were known to be ...

Another one of these has come my way and I am offering it again at the same price $700 net of paypal fees. Shipping not included. In unopened factory carton. I could double box it and ship it anywhere. This is probably about a $1500 unit if bought from AmScope. LSS has better QC. They are part of WW...

I found a home for this scope. When I set it up I was fairly amazed at the quality of it. There were some rough looking edges here and there but in places where it counted things looked very good. If anyone is interested I probably can get more of these. I did not do the phase ring alignment nor che...

Chinese made Phase Contrast Scope

For sale is a new in the box never opened (I can open it and QC it for a buyer or you can take it sealed and have your own "unboxing" party) Phase Contrast Trinoc scope. This is branded Lab Safety Supply which is a subsidiary of WW Grainger. It is probably similar in quality to the education level s...

The M5 is the last model with completely hand fitted focusing racks. The university where I work bought a bunch of them in about 1967 and many of them are still in service. I have on occasion attempted to consolidate broken pieces into working scopes, and this is almost impossible on the M5. The two...

Kinetic Systems benchtop active anti vibration system NIB

I think I have decided to sell a New In the Box , never used nor unpacked KSI (Kinetic Systems) anti vibration work station. If somebody bought it,it would arrive in the manufacturers' original packaging which would be strapped to a pallet. It is a KSI Model 2212-03-11 It is two feet by three feet a...

You should ask the parts department at Leica Microsystems in Chicago. If they can't help you then you will need to remove the broken part and have a machinist duplicate it. If you find a rack gear with the correct pitch and size you may be able to start the machining process using that. If you can f...

Since seeing the propaganda on the AZ100 I presume that it would be lots of fun but I have never run across one in person. At the new price I think they will remain rare and expensive even used.

The AO Cycloptic was had a barrel mag changer and claimed to have an APO corrected objective though with initial mag of no more than six or seven X this does not really mean much. But it was one of my first favorite scopes and I always liked it better than the Bausch StereoZooms and even the AO Ster...
