SWIR applications require special lenses that allow wavelengths from 800 nm to 1200 nm to transmit. Creating these requires lots of calculations and glass that has a specific coating.
Kowa offers a complete series of lenses that are specifically tailored to SWIR, with focal lengths ranging from 8 to 50 mm. With an image circle of 1" (25.4 mm) these lenses are ideal for large sensors, making them suitable for a wide range of applications.
The quality of the lenses (metal housing, metal mount, high quality glass and special coating) ensure that they can withstand rough industrial applications.
