Hyperspectral Lenses

NIR Lenses

The NIR objective fore lenses are optimized for the near-infrared wavelength region, 900 – 1700 nm. If better performance is needed, the Enhanced SWIR lenses are also optimized for use in the NIR region.

When choosing between the NIR lenses, consider the desired magnification. The lenses in the NIR series offer a range of focal lengths (8 – 50 mm) and have field of view angles between 10° and 58°.
