Anti-reflection (AR) coatings are applied to optical components to increase throughput and reduce hazards caused by back-reflections.

Optical coatings are used to influence the transmission, reflection, or polarization properties of an optical component.

This comparison of the performance of aspheric, achromatic, and spherical PCX lenses in different situations reveals the ideal use cases for each type of lens.

Optical Engineer Andrew Fisher explains how you can see the "invisible" light, or infrared light, from your own TV remote.
