Re: Assorted algae

Thanks Hobbyst! Yes, this is done with phase contrast (taken with a 40/0,75 Neofluar Ph2).

Its a fortuitous assembly of algae, the one and only occasion where I saw such a thing. I'm a bit puzzled as to how it happened.

Very interesting behavior. Do you know what causes the amoeboids to change to a pear shape and swim away?

Peritrichida

Went to my favorite spot a couple of days ago to collect water samples and found these peritrichs to be very abundant. They formed very large colonies on the side and bottom of the sample containers. Not sure about the species. https://kopame.com/dmqk/dmqm/media/peritrich4780medium.png https://kopam...

Re: Fluor vs Plan Fluor?

The correction collar on the Fluor objective is probably there because of the high N.A. The Plan-Fluor has a lower N.A. and therefore doesn't need such stringent control over coverslip thickness. If you plan on doing photomicrography I'd go with the Plan lens. If you just look for eye candy on the g...

Re: Diamond surface

Stunning! Is there a special name for the triangular structures visible in these photos and how did you produce the colors in the second image? This is all very, very interesting, a bit more detailed info on your epiDIC setup would be greatly appreciated as I'd like to invest in one.

Re: My Zeiss Universal Project

Very cool thread Microworldofgems! The paint job is great and I find your prism repair inspiring. Would Canada balsam work for gluing the prism wedges? I noticed you removed the optovar from the tube head. I had the impression once its off its nearly impossible to get it back to its original position.

Re: Zeiss DIC- could this work?

I'd make a guess and say no. I tried to use the dedicated prisms for the INKO condenser you posted in an epi-illumination setup and it did not work at all. Still, give it a try I'm curious to see what you come up.

I got into microscopy as a hobby a few years ago, and, frankly, it's been mostly frustration for me since then. Almost all of this frustration has resulted from equipment issues.
