OPT Machine Vision’s 20MP Dolphin lens series delivers high-resolution images on camera pixels as small as 2.4µm, up to a sensor format of 1.1″ (image circle diameter 17.6mm). The focal length range extends from 12 to 50mm. An optimized surface coating allows transmission from the visual to the NIR range (400 to 1000nm). The smallest setting distance of the C-mount objectives is 100mm for the 12mm objective and 250mm for the 50mm objective. Additional color or polarizing filters can be mounted by means of fine thread.
