How To Measure Thin, Parallel Optics
 
By Dan Musinski, Zygo Corporation

Thin, parallel optics are difficult to measure, because both front and back surfaces reflect light. Fourier-transform phase shifting interferometry can separate those reflections and provide more information than traditional methods.

5 Reasons Collaborative Design Produces The Most Innovative Products
Article | SCHOTT North America, Inc. - Lighting and Imaging

Designing robust products with fiber optics components for everything from medical instruments to jet planes not only demands optical considerations, but also thermal, electrical, and mechanical requirements. 

Do You Know What You Are Really Buying?
Article | Schneider Optics

Datasheets can be misleading, so how do you know what you are really buying? To help optical designers and engineers view optical datasheets more critically and ask the right questions of lens providers, this article discusses key datasheet parameters.

Laser Illumination For High-Speed Imaging
Article | Photron, Inc.

An incorrect or poorly lit subject affects the image, regardless of camera system quality. Therefore, the illumination source is just as important as the camera's resolution and sensitivity. See how a laser can be used for illumination in these four high-speed imaging application examples.

Understanding Detectors With Thermoelectric Coolers
White Paper | Opto Diode, An ITW Company

In order to optimize a detector for enhanced performance levels within their designated applications, it is important to understand the heatsinking of the package. A detector’s thermal resistance is minimized by the proper heat sink selection and mounting by using a thermal interface material.
