In order to make highly clear dot measurement for various night version fields, a lot of users would prefer to make dot measurement with a long wavelength device of Berlinlasers 980nm infrared laser diode module. It is applying a metal heat sink cooling system and APC, ACC driving circuit board. In process of long lasting IR dot aligning within 8 to 10 hours, it assures good thermal emitting, and highly reliable IR dot indication within long extending distance of 100 to 1000 meters.
Only after proper use of 5V, 9V 1000mA AC/DC adapter, and special use of extending electric wires, this 980nm infrared dot laser module enables freely installed distance of 3 meters. It makes easy and long lasting dot alignment, without light decay or blur. After its freely adjusted laser beam focus and IR dot projecting direction, and correct use of output power, it brings users high precision and high stability infrared dot generation for military targeting, infrared laser sight, scientific experiment and high tech work etc.
