Hyperspectral Lenses

SWIR Lenses - Enhanced Series

When choosing between the SWIR Enhanced Series lenses, consider the size of the samples and the desired magnification. The SWIR Enhanced Series offers a range of focal lengths (9 – 56 mm) and field of view angles (9 – 52°). For process applications, a larger field of view angle is generally better because it collects more light and the camera can be placed closer to the sample.

Additionally, the SWIR Enhanced Series offers the OLES MACRO lens, which is ideal for imaging very small samples at high resolution. For example, from a working distance of 10 cm, one can view an object that is only 1.2 cm in length.

* 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.
