Understanding LIDT Laser Optics For High-Power Lasers
 
By Gooch & Housego PLC

To analyze the specific damage characteristics of high-power laser optics, it is important to understand the laser induced damage threshold (LIDT), an analytical threshold determination method that can reveal damage diagnostics, and its testing provides a lower-cost option for coating development. This paper details the different test types of LIDT, how to measure the optical thresholds, how to identify defects within high-power lasers, and more.

Understanding Detectors With Thermoelectric Coolers

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.

Phantom Miro C110 Camera

Vision Research presents the new small, flexible Phantom Miro C110 camera designed to operate in a wide range of applications including industrial trouble-shooting, mechanical analysis, motion analysis, and any other application requiring high-quality, high-speed imaging analysis. 

Why SWIR And InGaAs Are Useful

Sensing in the shortwave infrared (SWIR) range (wavelengths from 0.9 to 1.7 microns) has been made practical by the development of indium gallium arsenide (InGaAs) sensors. This white paper covers the importance of using InGaAs technologies in SWIR applications.

Designing A New Optical Projection Device For Military Pilots

When the Department of Defense decided its landscape flight simulators to train pilots required too large a display, too large an enclosure space, and felt a bit antiquated in general, the DoD looked for a helmet-mounted simulation solution to replace the traditional rear-projection screens they were using.

Pulsed Laser Diodes At 1550 nm

LASER COMPONENTS designs and produces PLDs at 1550 nm with high-power levels up to 50 W. This wavelength cannot be detected by common night-vision goggles, making the PLDs ideal for multi-junction pulsed laser diodes within military laser rangefinder and friend/foe identification applications.

CMOS Sensor Family
 

The 120-megapixel CMOS sensor has a pixel count equivalent to the approximate number of photoreceptor cells in the human eye. Recording capabilities at approximately 60x the full HD resolution of 1920 x 1080 are made possible by parallel signal processing, which reads signals at a high-speed from multiple pixels. This sensor has a size of 29.22 mm x 20.20 mm, a square pixel arrangement of 2.2 μm x 2.2 μm with 122-million effective pixels, and 28 digital signal output channels.
