Description
The SWIR Enhanced Series from Specim 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.

* 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.
