Tiny organisms illuminated with polarized light

In Life in a Different Light, above, Denmark-based YouTuber and microscopy enthusiast My Microscopic World uses polarized light to illuminate microscopic creatures. The footage was taken with an iPhone mounted on a modified microscope with a LabCam adapter.

The results are vivid and revealing “due to a phenomenon called birefringence” or double refraction.

“One type of organism that reacts well to the polarized light is insect larvae. This is because the exoskeleton of these animals is made of a birefringent polymer called chitin. As the larvae move, each individual body segment gets aligned differently in the polarized light, which makes it look like the segments are changing colors.”
