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.

Determine how to select an optical window based on its material transmission, thermal and mechanical properties, and other specifications at Edmund Optics.

Optical Windows provide protection between an optical system or sensitive electronics and an outside environment.

Choosing the right optical glass is important. Find out factors and properties on how to select the right optical glass at Edmund Optics.

The surface quality of optical components the scattering off of its surface, which is especially important in laser optics applications.

A protective plastic coating protects a variety of our flat optics, such as optical windows, optical mirrors, and beamsplitters, from scratches during shipping.

An understanding of refraction and basic ray optics is a critical foundation for understanding more complicated optical concepts and technologies.

Edmund Optics® (EO) manufactures millions of precision optical components and subassemblies every year in our 5 global manufacturing facilities.
