The tube fittings on the bottom ring are probably water inlet/outlet for temperature control. Maybe from an automated wafer inspection scope?

Don't recognize that model, but the physitemp stage is really cool. I use a similar tabletop leitz freezing microtome hooked up to CO2 and its a pain to use. Good to know theres a retrofit option out there... I also have a ton of 12cm knives from various manufacturers, mostly C type. If you ever nee...

PM Sent thank you

HI yes I have multiple available but hoping to ship to US only.

Pau,

Good idea, it would be tricky yes but layering or using just the color channel over the sem image could work, no idea how to do it. Not good at photoshop or similar, but I'm realizing its something I need to learn.

Hi Rik these were dehydrated in ethanol, dried further with supercritical CO2 (critical point drying) and sputter coated with a Gold/Palladium alloy.

They were the typical purple and white urchin color before sample prep. Still trying to figure out how to add the color back in...

Thanks! I realize now I should clarify: top photo shows the spines as found, the 2nd pic is a spine cross section ( seen out of focus in top left of first pic)

Sea Urchin Spines found in tidal pool sediment. Very small probably about 0.25-0.5mm across and 3-4mm long

I have one of these photo tube assemblies for sale with the correct 10x eyepiece (red dot) if you are interested I can send some pics.

i honestly think someone must have seen rotifers and used them as the inspiration for many of the evil flying squid robots in the Matrix movies. Great shots.

Love them all but the first one is great! Tis the season!

Interesting, thanks for the link. New images look great!

Both samples cleaned with sulfuric acid. Diatom imaged on olympus bh2 at 200x DIC, Circuit imaged on Zeiss Photomicroscope 200x INKO. Both about 10 image stacks, sharpened in gimp.

How do you color? Photoshop by hand or a script/program?

Thanks

Hi can anyone ID this diatom found in filtered seawater? Sample collected off Malibu CA. Unfortunatley the filter used did not allow for good digital images. Therefore this was taken directly from the SEM screen with phone camera. Thanks!
