Re: Gel with specific refractive index

The last one i use who doesn't work because on high magnification it shows a kind of granulometric texture and a light blue color was "Ultrasound Gel by Liquasonic". However, the consistency was great as it doesn't spills from the specimen holder "sandwich". The one i am using for quite a while now ...

Gel with specific refractive index

Hi, i shoot inclusions in amber and for versatility purpose, i rather install specimens between 2 microscope specimen holders (glass slices) covered with gel in order to "flaten" the field of view, than emerged on a liquid.

Most low power microscope objectives don't work particularly well for photomacrography. I've had good luck with the Olympus M Plan 2.5, but otherwise all the objectives I've tried below 3x have been a disappointment. Even the Mitutoyo M Plan Apo did not do well vs some other lenses in the 2x range....

Lomo 2.5 - 0.05 Experience

Hi, Does any one have experience with the Lomo 2.5 - 0.05? A friend gave me one yesterday and at first sight it shows a lot of chromatic aberration. I try this lens on a PB6 bellow with +/-160mm extension, images are really not sharp, working distance is very short btw. I'm just curious of the setti...
