Re: Zeiss 100w Halogen bulbs
I would try a KG3 filter first. It is thicker than the KG1 hence it blocks more IR. These are absorpion filters, so transparency to IR depends on the thickness. All filters in link are 2mm thick ...?

Re: Zeiss 100w Halogen bulbs
The other possibility is " beware of staring straight at the lamp filament or beam". Sorry, concurrent posting - does look like a lamp filament!

Re: Zeiss 100w Halogen bulbs
Like any other halogen bulb it produces an quite significant amount of IR. This is why those lamp houses came with heat filters. If you have one of the Illuminator 100 lamphouses can you point out the heat filter for me. Only glass between the bulb and the microscope that I can see is the focusing ...

Zeiss 100w Halogen bulbs

Anyone have an original 100w bulb 380059‐1660‐000 with box for the illuminator 100 ?
Interested if there are any UV and/or IR warnings on it
These are some I picked up a while ago (they are meant to be equivalent replacements) but have not used yet. Seems to warn about everything!

Re: Leviathan ID (segmented aquatic worm)
Yeah I was doing that the whole time but I was using water from the specimen jar which leaves hard water stains (or could be salt - not sure, this creek does connect to the SF Bay) when it dries so I'm wondering if maybe I was slowly raising the pH over the several days I kept it and was tending to...

Re: Objective hits the glass
Different models of objectives can have different working distances, but I believe 0.1mm is what most of mine are designed for. It also depends on the thickness of the coverslip and how far down into the mountant the structures you're looking at are. That ( in bold ) is the point. Objectives are de...

If you are using a wet mount (i.e. observing Pond life) then you may have too much water under the cover slip.

Just checking my notes again, don't know if it will help with the ID but width is 210µm rather than the 170µm posted on the video.

Very nice!
Can you confirm whether indicated areas are Rimoportulae or Pseudonodulus? (See below)
Also, what process do you use to separate the diatoms from the Diatomaceous earth.
And last but not least, how does your sample offer work?

As long as they fit snugly in the eyepiece tube, (most are 23.2mm) then any make will do.

Rather than one long worm what you seem to have is a family! I counted 8 buds. I believe it is known as paratonic fission.
