It’s not a perfect build, but the concept is intriguing: using polarized light and stress-induced birefringence to generate colors without resorting to RGB LEDs. The clock uses white LEDs to ...

The Field Museum in Chicago and the Foundation for Scientific Advancement reported that sediment-encased maturation of pine ...

Plane polarized light (PPL) reveals the general hue, habit, and pleochroism of the crystal. Extinction angle and birefringence can be measured using crossed polarized light (XPL) in numerous ...

Birefringent crystalline materials are essential in advanced optical technologies such as isolators and modulators due to their ability to manipulate light ... with a birefringence value (Δn ...
