Ethan,
Thank you for describing existence of two types of polarizers. I use two
crystal imagers/incubators, a smaller machine is easy to adjust to compensate
for birefringence of plastic plates/covers, another is more capricious and the
compensation is uneven over a plate. Company engineers expl

If only glass is placed between the polarizer and analyzer, the crystal will
not show artificial colors (try it in a 9-well Pyrex depression plate). The
artificial colors come from the diffraction of visible light from the plastic
ware, which depending upon the type of plastic and the way the pl
Hi All,
Adding some more details to what's been said already. Only because I've
seen too many times the polarizers being used incorrectly.
First, you need two polarization filters which are typically called
polarizer and analyzer. First one (the polarizer) lets through only the
light waves of a ce

Hi all,
The polarizer-microscope in our facility is not working properly, and I have
to check my plates using a standard stereo-microscope. As a workaround, I
thought about buying one at Amazon, placing it on top of the plates and
rotating it to still test for birefringence.
