Natural Science Forum / Physics / Optics / September 2007Reichert objectiv replacment, leica or AO possibly
Is there a knowledgable expert out there that can help a new beginner in replacing the missing objectives on a Reichert Microstar IV. I have been having loads of trouble sourcing the objectives that I want and was hoping that there is an equivilant to the Reichert made by either Leica or the American objectives that will work as well as the Reichert. Apparently Reichert, Leica and American Objectives are or were all at one time part of the same company. If anyone knows that there are some of the objectives are interchangable what woud be the make and catalog number for most importantly the #1730 2.5X Plan Achromatic, #1731 4x/.10 Plan Achromatic, and #1732 10X/.02 Plan Achromatic, and for a later date (when i can afford it) #1733 20x/.50 Plan Achromatic, #1734 40x/.66 Plan Achromatic and #1736 100X oil Plan Achromatic? The manual states the objectives for the microstar IV listed below are as follows with # denoting the catalog number... #1727 10X Plan Flour. #1728 40X Plan Flour. #1730 2.5X Plan Achromatic, #1731 4x/.10 Plan Achromatic #1732 10X/.02 Plan Achromatic #1733 20x/.50 Plan Achromatic #1734 40x/.66 Plan Achromatic #1736 100X oil Plan Achromatic #1742 10x/.25 Phase Plan Phase Achromatic #1743 20X Plan Phase Achromatic #1743 20X Plan Phase Achromatic #1744 40x/.66 Phase Plan Achromatic #1749 100x/1.25 oil Phase Neo-Plan Achromatic #1750 10X Plan Phase Achromatic (ATC2000)New #1751 40X Plan Phase Achromatic (ATC2000) New #1752 20X Plan Phase Achromatic (ATC2000) New #1753 100X Oil Plan Phase Achromatic (ATC2000) #1754 10X Neo Plan #1757 40X/.66 Neo-Plan Achromatic #1758 50X/.80 (oil) Neo-Plan Achromatic Many thanks for any help tim On Sep 13, 2:36 pm, timevi...@hotmail.com wrote: > Is there a knowledgable expert out there that can help a new beginner > in replacing the missing objectives on a Reichert Microstar IV.

The 410 was the crappiest microscope ever produced by the hand of man so you don't want any, thats any, AO 410 objectives. The Reichert plant is just outside Vienna and they don't produce microscope any more. Now just to buck you up, you can probably switch the microscope over to either Olympus or Zeiss objectives. Both brand are infinity corrected and use the RMS specification for the screw thread. You will probably have to switch completely over to the new microscope objective brand for parfocality reasons. Your alternative is the used market. There is a repair facility just outside Buffalo, NY that is run by two ex-AO people, they bought the last stock. I doubt that they have any objectives though. Try Googling them. Thanks Kevin Cunningham SMS Thanks Kevin, it may hurt but it is good to know, I was hoping to get some pictures and have one with a trino head and apperture controll system hooked up to a modern dSLR and so hopped to get something out of the setup. It may well be time to cut my losses though :-|. tim Sometimes Kevin is right on the money, and sometimes his bias in microscopes that's based on his years in service creeps up (Seeing broken or heavily used instruments all day tends to sometimes cloud the judgement). While the 410 wasn't a great scope, and mechanically it's made of fairly cheap materials and construction, it's still a useful instrument, and they still sit on many pathologists' desks. What I don't think that Kevin realizes is that there were some *very* nice objectives made for that instrument. In particular the 10x and 40x plan fluor were *amazing* objectives, and until the late 90's were still being hand made in Vienna. The successor of the 410 was Leica's "ATC2000", any objective from that series will work in the 410. The 410 uses infinity corrected objectives with an RMS thread size. You could probably pick up some decent objectives from Meiji, Olympus, or Zeiss that will work surprisingly well, OR you could luck into some of those great Vienna Fluors. I cannot stress enough how great those Fluors were, I would compare them against ANY of today's top manufacturers' objectives and I suspect they would come out on top. Call a local microscope company that deals in used instruments and ask them if it'd be ok to come in and try a few objectives. They should be happy to help. Incidentally, the folks that Kevin is talking about is... Cambridge Scientific, you can reach them at (617) 354-8900 > Incidentally, the folks that Kevin is talking about is...

I have [quoted text clipped - 39 lines] > > tim Two more points: I think AO stands for American Optical (Company), not American Objectives--this may help in your web searches. At some points in time, the Spencer Lens Co. and AO merged to form AO Spencer (long ago); then, AO, Reichert, Leitz, and possibly Cambridge Instruments, were merged into what is now Leica USA. Also, the AO Series 10, 110, and 120 were pretty good scopes, infinity corrected, and their lenses are readily available on eBay and elsewhere. I think they might work fine on your scope for general use (plan achromats sell on ebay for $20 - $50 ??). Good Luck I've had several AO scopes, and think they offer good used value. Bob Marable I have three Reichert objectives. The 10x,40x and 100x oil. They have a infinity symbol/ 0.17 cover glass thickness. I can send you an email with pictures if that is OK and you can make an offer. I have a trinocular head with a place to add a epi illuminator. My Reichert microscope needed too many repairs. I saved some of the parts. > Is there a knowledgable expert out there that can help a new beginner > in replacing the missing objectives on a Reichert Microstar IV.

I have [quoted text clipped - 39 lines] > > tim Tim, I need and want to agree to what Kevin told you - I worked at Reichert in Vienna for many years in the 80's and have been responsible first for their application lab and then for marketing and technology - when they still had been in the business of microscopy. The 410, which came out of Buffalo is not a good microscope and certainly not worth upgrading or enhancing - put it onto a shelf in a very private room and think about it as something which a certain company in Buffalo called a microscope. Get a good one and enjoy it for many years - Nikon, Olympus etc. Best regards (Prof.Dr.) George Nyman |
