They don exist in real world - yet - I'm preparing the meshes (3d models) for 3d printing right now :) For now, this is just computer graphics "art" :)
I missed the first line in the initial post and was ready to chow down. Impeccable realism!

Re: Spirogyra - Christmas spirit

Cool microcompositon! What were your excitation/emission parameters? Excitation Filter: 330 – 480 nm single band bandpass filter Dichroic Mirror:495nm Emission Filter: 500nm long pass edge filter Oh wow, you're really blasting them with short wave! Is that a standard set or something you cooked up ...

Re: Any Colour You Like

Interesting, could make a nice Christmas image. Very nice. How did you add in the colours? :D Thanks! Colors are the result of taking advantage of my Abbe condenser's chromatic aberration. Oblique filter at the iris, then decentered and defocused to cast the light to line up just right. Such a nega...

Not an edit! Well, not a major edit, anyway. Just some little touchups.

Re: Darkfield Diatoms

Yeah now to be fair, I've done a good bit of post-processing here to make this pop and to crush the background to true digital black. Here's an image that better represents what you'd see through the viewer. Still, I find that if I expose for the bright points, the camera crushes the background clos...

Re: Darkfield Diatoms

That's some nice crisp darkfield! Well done. Thanks! This was done using an Amscope DK-DRY200 darkfield condenser on an Olympus BH2. It works great despite the manufacturer mismatch and is a fine addition to my ever growing collection of microscopy accessories. Will be trying out the DK-OIL200 soon!

Re: Euglenids

Hi Robert, big fan of your photography work! I've been referring to a lot of your rotifer photography when I'm trying to identify species I find in my specimen jar. Do you ever use thinner cover glass for thicker samples? Thorlabs sells high precision #1.5 and #0 cover glass for decent prices (plus ...

Closterium moniliferum

Did this a couple months ago. Picolay focus stack on an amateur microscope. Probably using a 10x or 20x SPlanApo lens and a Varimag. People talk about how the olympus lenses need corrective eyepieces but I haven't found that to be particularly true in all cases. Might be lower magnifications or fiel...

Hello from San Jose!

Hey folks, I'm Jason - I've been involved in optics and biology for a while now as part of my engineering career but I'm just recently getting into amateur microscopy as a hobby. Right now I've got a Journey to the Microcosmos microscope, a Swift 380B, two Olympus BHTUs, and one BHT with an RFCA ill...
