Would a monopole work on hydrogen horn if added on back panel of waveguide coming straight into horn rather than from side of waveguide?

Admin August 17, 2026 No Comments

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…

What is the frequency for 22ghz water masers?

Admin August 17, 2026 No Comments

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…

Zeiss IM35 microscope fluorescent cubes – suggestions for microscopy at LRO

Admin August 16, 2026 No Comments

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…

What fluorescent dyes are good choices for my Zeiss IM35 inverted microscope?

Admin August 13, 2026 No Comments

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…

What else beside scales would be useful for preparing fluorescent microscopy stains such as FDA?

Admin August 13, 2026 No Comments

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…

What is a good choice for laboratory scales for microscopy?

Admin August 13, 2026 No Comments

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…

Most appropriate fluorescent stain when aim is to stain particular structures in cells.

Admin August 13, 2026 No Comments

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…

Rubidium Time Standard

How do you check rubidium source gets rubidium lock?

Admin August 12, 2026 No Comments

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…
