measurements of Reichert Zetopan deviating prism lever

Post by brettpim »

As I get to know my Reichert Zetopan, I am posting things I figure out that are not (as far as I can find) easily found on internet. The lever for moving the deviating prism between the binocular/monocular eyepiece tubes and photo tube on a Reichert Zetopan has the following dimensions:

M2x0.4 thread of length 2.5mm
3mm diameter rod for 19mm
handle of length 10.5mm
total length 31.9mm

My friend with a machine shop says that even with the appropriate die, it is very tricky to make such a small thread. These machine screws on ebay are suitable replacements. The hex-head has a knurling so it is convenient to hold.
