Re: Microscope fan cooled illuminator

Sorry, No ... It is something I would avoid on principle. I suppose if you have a very heavy microscope and a very small fan the effects might be undetectable ... But is it worth the risk ? MichaelG. Do you mean something like an external 150w illuminator with a fiber optic light guide? Those are a...

Hello Saul,
there is a Leitz brochure 'Fluorescence Microscopy - Instruments, Methods, Applications' which includes the data for the barrier filters you are asking for.
I found mine as PDF in the web.
Any chance for the direct link ? Or document itself ?
Thanks !

Not too small for the seed ? Forgot to mention - it was almost transparent Surprisingly, no. Using a stage micrometer, the grass seeds measure out to the same dimensions you noted: ~ 0.5 mm long x 0.25 mm wide. They are teeny tiny seeds, but not quite as pointed on the one end as your 'thing' is. I...

Re: The Thing

These look similar in size, shape, and color to sedge grass seeds (species info unknown) that I collected today alongside the pond. The tiny seeds were contained inside larger black husks, which I initially mistook for the seeds. I did not see hexagonal patterning but didn't look that closely eithe...

Re: Dimmable LED/flash microscope illuminator

Hi Saul, this is a very nice looking product! I'm sure that will be able to sell a lot of them at the given price point. Is it necessary for these microscopes to have the light source exactly at the original position or is there a frosted surface in the light path that acts as the light source? Bob...
