New Kowa lenses with transmission from VIS to SWIR

At the beginning of 2021 Kowa launches lenses with a transmission of 450-2000 nm. In this wavelength range, the lenses also have a reduced focus shift.

NIR-SWIR cameras and hyperspectral cameras can precisely analyze the reflection properties of materials over a wide range of wavelengths. This is often used in image processing for material inspection and sorting.

For example, during an inspection in the food industry: appearance inspection of fruit in the visual range and internal inspection at 1400 nm (illumination). Without a VIS-SWIR camera and optics, users may need to adjust the focus by changing the illumination and changing the lens.

With Kowa's VIS-SWIR lens, production time or the adjustment process can be shortened.

Kowa is initially launching lenses for the 1" format with focal lengths of 12mm, 25mm and 50mm. Further focal lengths are planned.
