Product Description
Specially designed for the medium wave infrared band (MWIR, 3.7~4.8μm) prime and zoom lenses, the MWIR series lenses are suitable for the MWIR cooled detectors and come with near diffraction limit performance. The products cover fixed focus, dual field of views, continuous optical zoom and other specifications, with high transmittance, strong temperature adaptability, and stable imageries amidst zooming. Thus, they are a good choice for remote vision, high sensitivity, better signal-to-noise ratio and atmospheric transmission.
The production and development can be customized according to the client's requirements.
