ADVICE FROM CHATGPT: The Zeiss IM35 was originally designed to accept interchangeable fluorescence reflector/filter blocks, and I’ve found period evidence for several combinations actually used with the IM35. The most…
This is a combined document, containing the latest version of the Manual from August 2026, when I visited the telescope, and the 2017 version of the Manual, which contains some…

Yes. The Zeiss IM35 can make a very capable fluorescence microscope, but the best dyes depend primarily on the fluorescence filter sets fitted to your particular IM35, rather than on…
For preparing small quantities of fluorescein diacetate (FDA), I’d get a few inexpensive laboratory consumables. You don’t need elaborate equipment. For your particular setup, I’d start with micro-spatula + weighing…
Yes — a good used laboratory balance from eBay can be an excellent choice, particularly compared with inexpensive new “milligram” pocket scales. For weighing 50 mg (0.050 g) of fluorescein…
Certainly. If you’re experimenting with fluorescence microscopy, I’d choose the stain according to what you want to see rather than buying fluorescein disodium first. What you want to examine Good…
For a rubidium frequency standard, there are usually two separate things to check: On most rubidium modules, the best indication is a dedicated LOCK / UNLOCK / STATUS output. After…
On the Olympus/OM System OM-5 you can set it to manual focus (MF). The simplest way: You can also make manual focusing much easier by enabling Focus Peaking, which highlights…
It’s called exposure compensation. For example: On your OM-5, you’ll normally see it displayed as ± EV, with a scale such as –3 … 0 … +3. If you’re trying…
