[Via Satellite 08-25-2015] Lockheed Martin scientists have improved threefold the power density of the company’s High Power Microcryocooler. The new system cools optics and electronics to as low as minus 320 F (minus 195 C) while maintaining roughly the same power efficiency rating as lower-power coolers.

Highly sophisticated electronics often need to be cooled to detect what they’re designed to capture. Lockheed Martin’s microcryocooler can be used to support larger, more sensitive Infrared Radiation (IR) sensors, useful for very high-resolution images. The company has reduced the size of the component as well.

The High Power Microcryocooler delivers more than 150 watts per kilogram, and weighs less than a pound. The device is designed for continuous operation over a lifespan of more than 10 years.
