Hyperspectral Lenses

VNIR Standard Lenses


The VNIR (visible near-infrared) Standard Series lenses are available in a range of focal lengths (8 – 50 mm) and field of view angles (10° – 58°). When choosing between the VNIR Standard Series lenses, consider the size of the samples and the desired magnification. For remote sensing or field applications, a larger field of view angle is usually preferable.

* Default slit width (30 µm) chosen for calculations. Standard 2/3" detector limits effective slit length to 8.8 mm.

** Full field of view angle may not be achieved if distance is shorter than the given minimum working distance.
