The use of near and far infrared laser diode modules covers wide range wavelengths of 780nm to 1470nm, available with various output powers within 5mW to 1000mW, making sure of high quality infrared laser light source emission. It makes good use of thermal emitting system and proper use of night version device or instrument, not any longer relying on manual labor force input, infrared laser always bring users highly clear and accurate infrared dot alignment and measurement for all night version application fields.
