HD Lenses

Our HD lenses are optimized for a resolution of 1280 x 1080 pixels with a pixel size of 12µm. These lenses have a cold shield height of 25.4mm (1 inch). They provide a high resolution of up to 42LPMM, maximizing the performance of your 12µm HD Array. Additionally, these lenses are compatible with the Janos IR bayonet used by Pulsastrix and Asio lenses. Furthermore, they incorporate the same warm filter feature as the aforementioned lenses.
