L-3 Communications Cincinnati Electronics (CE), the Army Research Laboratory (ARL), and the Army Night Vision and Electronic Sensors Directorate (NVESD) have been developing the corrugated quantum well infrared photodetector (C-QWIP) technology for applications in tactical LWIR imaging. The C-QWIP was invented at ARL and shows promise to overcome some of the limitations in commercially Owing to its good linearity, this sensor can be applied to measure medium pressure, liquid level, and depth underwater.

We hire creative problem solvers who want to support their nation and enjoy a rewarding career.This approach extends to a range of legacy, emerging, and future military propulsion, power and thermal technology needs in multiple applications. Work will be performed in Redondo Beach, California, and is expected to be completed by Feb. 8, 2027. This award is the result of a competitive acquisition and 54 offers were received.Snakes slithering across the desert sand at night can encounter obstacles such as plants or twigs that alter the direction of their travel. While studying that motion to learn how limbless animals control their bodies in such environments, Georgia Tech researchers discovered that snakes colliding with an obstacle behave much like light waves encountering an optical diffraction grating.At McNICHOLS we carry a wide variety of Bar Grating.

Robust and versatile, light-duty steel grating is used for a variety of applications. Examples include: Walkways; Bridge & highway platformsIn this paper, micromilling was used to process the surface of single crystal silicon, and six different structural parameters of the grating structure were tested to get the contact angle in a different wettability. The contact angle obtained by the experiment was compared with the theoretical values of the Wenzel and Cassie model optimized based on the characteristics of micromilling.
