In those of special scientific research fields, a lot of engineers and professionals would prefer to operate a longer wavelength device of a 980nm infrared laser line generator. It is primarily used in the fields of optics, materials science, biomedicine, 3D measurement, and optical communication. It always applies qualified import 980nm infrared laser diode and glass coated lens inside a durable metal housing tube, configured with basic thermal emitting design, this direct diode emission made infrared laser module enables high precision IR line light source emission, strong resistance to light interference. When it makes easy integration with scientific experimental device or equipment, it always enables highly precise, fine line indication, applicable for multi-disciplinary precision experiments and long-term measurements.
This 980nm infrared laser line generator applies an AC/DC adapter as its electric power source, thus it always able to make quick response and good direction IR line projection onto any working surfaces. It applies an import 980nm infrared laser diode with 100mW to 1000mW, after special use of inner cooling system or separate metal heat sink design, it always gets superior nice heat dissipation, and ultra long time lasted infrared reference line projection within 10 hours. When infrared line laser module gets small laser beam divergence of less than 2mrad, it can get ultra fine line width of ≤1mm at 1 meter, meeting the needs of micron-level experiment. The 980nm invisible light is resistant to sunlight and indoor light interference, significantly improving signal-to-noise ratio with narrowband filters, suitable for continuous day and night measurements and outdoor experiments.
When 980nm infrared laser line generator is applied for biological and experimental safety field, owing to its high penetration IR laser light emission, it also allows easy location in the second optical window of biological tissue with low scattering, and minimal damage to cells and tissues. The invisible light gets no red glare, does not interfere with visual observation and imaging systems. Besides its operation with common DC power supply, this infrared line laser module also supports TTL modulation. This ultra compact size tube mde laser device can be directly installed on an optical platform, suitable for continuous and pulses dual modes and long term experiments.
