OB – SWIR 75 1 December 2014 Rev 002    LENS OB-SWIR75/4 – P/N C0415 General Description   This family of high resolution SWIR lenses image from 0.9 – 2.3 m making them especially wellsuited for PCB inspection, special laser applications, surveillance and alignment and tracking. A high F/N and excellent transmission characteristics allow superior imaging in these wavelengths of interest. Optical and mechanical parameters   Focal length Image format (diagonal) F.O.V.
