On condition that users are making ultra clear and fine line indication for specialized equipment positioning, engineers prefer to apply a long wavelength made device of TTL modulation 980nm infrared line laser module. It emits invisible and intense infrared laser light source directly from a 980nm infrared laser diode. Cooperated with night vision illumination machine or device, it converts into a visible and fine infrared reference line with various line lengths in use.
TTL modulation laser line generator adopts compact size and durable structure design, easily integrated with equipment or device. After its correct use of output power and optic lens fan angle, and freely adjusted infrared laser line thickness, it is suitable for scenarios where visible light markers are inappropriate, such as night-vision inspection, rail transit profile measurement, and marking for non-destructive testing (NDT).
