Until the time users are not able to make clear and accurate dot alignment under night vision illumination, it is a quite challenge work for user until selecting a quite professional dot measuring tool as expected. Laser tech engineer has never stopped on the step of formal manual dot projection or other visible laser devices, but beginning to develop a quite practically used dot alignment tool, such as 980nm infrared laser diode module. When it is emitting quite intense and powerful infrared laser light from beam aperture, after proper equipment with night vision device, such as a CCD camera, black and white camera or infrared laser camera, this infrared dot laser would make sure of quite easy and accurate IR dot generation in distance easily.
The operation of 980nm infrared laser diode module is not the same as formal visible laser devices, which is generating invisible infrared laser light and IR reference dot from beam aperture. In practical dot aligning work, this infrared dot laser is not able to used separately, under operation with night vision device, it is generating highly clear IR dot projection for special work fields, such as military targeting, surveillance, intelligence system and others etc. When 980nm infrared laser generates high photoelectric ability up to 80%, on basis of quite high power range of 100mW to 500mW, infrared laser dot would be clearly visible as long as 100 to 1000 meters in distance.
In order to get continuous IR dot projection on any raw material surface, 980nm infrared laser diode module begins to work immediately after easy connect with a DC input power supply. It is keeping work for majority of countries and regions. Within wide range electric current within 100V to 240V, this infrared dot laser is keeping work stably under multiple working occasions, including strong corrosion or high temperature etc. According to quite easy adjustment of laser beam focus, high concentration infrared laser light is temporarily focused, and then achieving the most compact size infrared dot projection in distance.
Including those of hard reaching places, the operation of 980nm infrared laser diode module can seek help from a laser alignment mounting bracket. Within freely installed distance of 0.3 meter to 3 meters, noncontact infrared laser dot is easy to reach any raw material surface, and then fulfilling high level of accuracy dot generation for all night vision fields. Under condition that invisible infrared laser light is produced from beam aperture, human eyes cannot capture any IR laser light at all. When users are paying high attention to IR radiation and IR reflection, after proper wearing of 980nm wavelength preventing laser safety goggles, this intense beam infrared dot laser would make sure of safe and clear dot measurement.
