F1.8 - F/16

Kowa LM-HC-VIS-SWIR lenses with a transmission of 450-2000 nm cover the range from visible to SWIR with the advantage of a reduced focus shift.

The lenses are suitable for a large number of applications with VIS-SWIR and hyperspectral cameras to precisely analyse the reflection properties of materials over a wide range of wavelengths. This is often used in machine vision for material analysis and grading.
