In some of special work fields, such as night vision military targeting, laser medical therapy, surveillance and intelligence system etc, it is always a very necessary part for users to use infrared laser devices. For instance, under operation of a long wavelength made 980nm infrared line laser module, and quite easy equipment with night vision device, such as a CCD camera, black and white camera or infrared laser camera, it is able to projecting the most intense and powerful infrared laser beam, converting into highly clear and easily seen infrared reference line projection under all night vision illumination work fields effectively.
The projecting laser beam of 980nm infrared line laser module is quite different from any formally used violet, blue, green and red laser module devices, which is generating invisible infrared laser beam and infrared laser line from laser beam aperture. When human eyes cannot capture any IR laser light directly, this IR laser line generator should not able to be used separately, but always operated as an accessory part. According to quite easy connect with a DC input power supply, this infrared line laser is just workable within wide range output power of 100mW to 500mW, which will make continuous and immediate infrared reference line projection in distance easily.
When 980nm infrared line laser module is required to produce extremely fine IR reference line from beam aperture, it is just being made with the best quality Powell lens. The separate crystal lens equipped laser line alignment tool is producing non Gaussian distribution infrared laser beam, and high uniformity and high straightness IR reference line in use. Especially in occasion of highly clear line alignment in distance, this Powell lens laser line generator is getting the best performance in use. In addition, under moderate accuracy line alignment, 980nm infrared laser should only be equipped with glass coated lens, after proper selection of output power and optic lens degree, it achieves high level of accuracy IR line alignment.
Owing to the employment of import 980nm IR laser diode, this direct diode emission infrared line laser module is always getting increasing stability in continuous use. When it is getting quite high power, it will make highly clear IR line alignment as long as 100 to 1000 meters in use. Under high attention to potential danger caused by powerful IR laser radiation and reflection, and produced thermal energy from beam aperture, this alignment laser should be properly used with on time wearing of laser safety goggles until achieving safe and easy alignment perfectly.
