Re: Calcite
They were given to me. Not all of them exhibit this result. They won't have birefringence, but regions of different thicknesses will refract differently, resulting in various dispersion colors. Maybe eBay, sorry I don't know. The attached micro-diamond images were generated with my Nikon SMZ-10. -JW:

Re: Software LoCA analysis
I wonder if ImageJ has that ability. Maybe ask in their forum.

Re: Calcite
Beautiful results - both on rebuilding the microscope and the images. They likely have you grinning ear to ear after all that work. Thanks. When I first got the SC and MET years ago, I was blown away by the images through the bino head. I have a couple of friends who own complete Polyvar SCs with t...

Conus traillii and Engina armillata
This was shot with my Wild Heerbrugg M400 Makrozoom using the 1:6 APOzoom and an old Panasonic GH3. I'm trying to get set up and testing my overall configuration and lighting challenges for a series of shell photographs (unless I get distracted). The Engina armillata looks like it had a rough life. ...

Re: Calcite
Hey Chris,
Thanks, I like the first shot too. Yep, you nailed it. They are my favorite scopes, for sure. I can't believe how long it took me to get these working.

Re: Made a quick-change objective system for my bellows
Interesting project. I have an old Pentax 6x7 bellow, but I haven't figured out what to do with it yet. Robert OToole and I were discussing this a few weeks ago. He suggested I contact Raf Camera to make new custom adapters for my Pentax. Robert had new SM2 threaded adapters that replaced the factor...

Calcite
I've been working on my Polyvar MET and Polylite SC for a little over three years, trying to get everything working. It seems like every time I would fix something, another issue popped up. Crazy. I've also succeeded in adapting my camera setup to each microscope, and they are both parfocal. Many of...

Re: Loss of Robert OToole
Wow, I'm totally blown away. What happened? We've corresponded a ton over the years. Robert was always generous and helpful. He told me he was super healthy. Had been on the Carnivore diet for a few years, Ketosis was excellent, his Glucose Ketone Index was scary good, and so on.
