You can feed a 1420 MHz hydrogen-line horn from the rear panel, but a straight monopole pointing forward down the horn axis would generally be a poor arrangement. The key…
For the 22 GHz water maser (H₂O) line, the laboratory rest frequency is approximately: 22.23508 GHz = 22,235.08 MHz Astronomical maser emission is Doppler shifted by the motion of the…
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…

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…
