Optical system consists of a high quality lens, which draws the infrared energy to the detector; a filter; and a field stop, which defines the visual cone and the minimum target dimensions. The detector is placed at the focal point of an optical system, so focusing operations are not required. Users simply aim at the target and read the temperature. Three types of pinpointing are offered: twin laser pointers to define, at distance, the measurable target dimensions; a combination of twin laser and direct telescope viewing for universal applications, mainly required for targets where certain distances are longer than 0.16'; or a combination of twin laser and red point pinpointing for universal applications, mainly required for high temperature targets where laser spots are not visible.
