MKS Instruments has announced that the Ophir SupIR 50-1350mm MWIR f/5.5 long range, motorised continuous zoom lens has been chosen as a 2020 PRISM Awards finalist. The PRISM Awards are an annual international competition that honours the best new optics and photonics products on the market. Nominated in the category of Safety & Security, this high performance continuous zoom lens is designed to provide ultra long range capabilities for advanced thermal imaging cameras in security and surveillance applications.

The Ophir SupIR 50-1350mm f/5.5 continuous zoom lens is based on a folded-optic design with the longest focal length of 1,350mm and a 27x motorised zoom ratio, suited for VGA and HD IR sensors.

The lens is optimised for stabilised payloads with capabilities for high resolution vision and identification in harsh environmental conditions and on constrained platforms while maintaining focus and tight Line of Sight (LOS) retention through the entire zoom range.

Such features open up new commercial and defence applications, such as visualising objects and situations that may not be visible to the human eye, for small size UAVs, threats at airports and state borders, gas leaks, and more.

"The unprecedented performance of the SupIR 50-1350mm f/5.5 motorised zoom lenses allows high resolution surveillance and identification in complete darkness over long distances of 25+km," said Kobi Lasri, General Manager of Ophir Optics Group.

"This recently launched zoom lens further expands our successful line of industry-leading long-range IR zoom lenses for cooled MWIR detectors."
