Leitz trinocular heads
Posted: Wed Apr 14, 2021 6:53 pm
There was a very useful post (here, I think) that described the later Leitz trinocular heads, their dovetail diameters, and eyepiece parfocal distance. One problem I have encountered is decoding Leitz product names into their part numbers. Example: FSA-GW-R, a trinocular head for the Orthoplan 2/Aristoplan. It takes the 30mm diameter eyepieces, the GW 10X/26M and GW 8X/28M. However, most of the Leitz trinocular heads show some part number on them, such as 512/815 20. Does anyone know of some sort of catalog or brochure that links these numbers to the product description? I have been trying to find the trinocular head that takes the 30mm diameter widefield eyepieces for the Aristoplan/Orthoplan 2. I see a lot of them (eBay) that I am sure are for the original Orthoplan (some descriptions actually say this and others give the dovetail diameter that is different from the Orthoplan 2 one), so none described as being for the Aristoplan, though some are for the later Diaplan (the 160mm tube length version) that might (?) be the same as the Aristoplan one.
