MKS Announces Ophir® Low-SWaP MWIR Lenses for Drone and Small Gimbal Applications

Tarih: Issue 122 - May 2023

MKS Instruments, Inc. has announced the Ophir® LightIR 10-135mm and 18-225mm MWIR f/3.6 continuous zoom lenses, the newest additions to the LightIR family of low SWaP (Size, Weight, and Power), high-performance, motorized continuous zoom lenses. Introduced at SPIE Defense and Commercial Sensing 2023, these lightweight, compact, thermal imaging lenses are optimized for smaller size VGA 10µm FPA (focal plane array) IR detectors.

The LightIR 10-135mm and 18-225mm MWIR f/3.6 lenses feature a compact design with reduced optical elements that significantly decreases the length and weight of the lens and, therefore, the overall size and weight of the optical system in which it is incorporated. The LightIR 10-135mm lens weighs only 250gr, making it 20% smaller than similar lenses and the smallest continuous zoom lens on the market today. The LightIR 18-225mm lens weighs only 300gr, making it also significantly smaller than similar lenses.
