In operation of highly clear cross line projection under night vision, it is not workable at all to rely on the use of manual cross line measuring device, such as formal triangular meter or blocking board. However, under continuous technical innovation of 980nm infrared laser diode tech and qualified glass coated lens with different fan angles, it is developing into a practically used device of 980nm infrared cross laser alignment. It should only be installing and adjusting to correct position, this cross line laser module achieves easy and highly clear IR vertical and horizontal lines with accurate 90 degrees effectively.
This 980nm infrared cross laser alignment makes advanced use of import 980nm infrared laser diode, within high power up to 100mW to 500mW. It is in need to make highly clear IR cross line projection continuously, but not simply used for temporary positioning work. Designing with quite durable and compact size tube diameter of 16mm and 26mm, after getting enough space for inner metal heat sink cooling system, it is achieving superior nice thermal conductivity, and highly stable infrared cross line laser source emission within wide range operating temperature of -10 degree to 45 degree Celsius.
Owing to quite advanced use of glass coated lens with different fan angles of 10, 15 and 110 degree, 980nm infrared cross laser alignment is generating different dimension infrared cross line source projection. It keeps work with high linear quality infrared cross line source projection, also getting no appearance of laser light decay or dim in continuous use. Whenever it passes through quite strict laser beam stability and special use of glass window in front of laser beam aperture, it just keeps work with stable IR cross line projection, without any affect by any moisture or dust at all.
In various night vision cross line projection work fields, 980nm infrared cross laser alignment enables gets the most special use of APC, ACC driving circuit board. It is preventing any increasing temperature and serious electric current impact, which is achieving up to 85% laser beam stability and long lifetime of more than 8,000 hours in continuous use. When users are making proper adjustment of laser beam focus and IR cross line projecting direction, only after high attention to laser safety issue and wearing correct infrared laser safety goggles, this alignment laser achieves highly clear and quick measurement in all night vision fields.
