Transparent Ceramics: Enabling Large, Durable, Multifunctional Optics
Mohan Ramisetty, Lee Goldman, Nagendra Nag, Sreeram Balasubramanian and Suri Sastri, Surmet Corp.

Single-crystal sapphire has been the material of choice for defense and other applications that require extremely durable optics, but aluminum oxynitride (ALON) and magnesium aluminate (spinel) have...

Common Infrared Optical Materials and Coatings: A Guide to Properties, Performance, and Applications
Jeffrey L. Tosi and Kumar M. Khajurivala, Janos Technology LLC

The optical materials selected for an optical system depend upon the application, the required system performance and the environment in which the system is to perform; thus the materials’...

Thin-Film Coatings: A Buyers' Guide
Trey Turner and Roger Kirschner, Research Electro-Optics Inc. (REO)

What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...

Optical Delay Lines: Key to Time-Resolved Measurements
MKS/Newport

One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...
