SWIR Lenses

Beck Optronic Solutions offers a range of high performance fixed focal length lenses and a zoom lens suitable for use in the SWIR (0.7 µm-1.7 µm) waveband.

Fixed Focal Length SWIR Lenses

SWIR_LENS.jpg

The lenses and thin film coatings have been designed specifically for the SWIR waveband.  Some suppliers offer "SWIR" lenses that are in fact visible waveband optics with only coatings optimised for SWIR. The Beck Optronic Solutions range of lenses is designed from first principles, with optical glasses as well as coatings optimised for operation in the SWIR waveband.  Importantly, the performance is validated through SWIR waveband MTF testing.

These lenses are ideal for many applications including security, inspection, quality control and machine vision.

Designed with an image format of 25.6 mm diameter, they are suitable for use with all the major area and linear array cameras available on the market.
