The LD Laser Module is primarily composed of a laser diode and a driving power supply. Compared to laser devices, the LD laser module offers advantages such as high efficiency, compact size, and long lifespan. LBTEK's LD Laser Module comes with a built-in collimating head, capable of outputting a collimated beam with a power of approximately ~5 mW at central wavelengths of 405 nm, 445 nm, 520 nm, 635 nm, 660 nm, 780 nm, and 1064 nm. The 1064 nm model outputs a circular beam, while the other models produce elliptical beams. Due to the varying power supply voltages required by different laser diodes, each laser module is paired with a DC regulated power supply (3V/6V). When purchasing multiple models, attention should be paid to voltage compatibility to avoid insufficient power supply, which may reduce output power or damage the circuit board. Specific beam dimensions and compatible voltages can be found in the detailed parameter table under each product model. LBTEK's LD Laser Modules feature stable power output, excellent anti-interference performance, high mechanical strength, durability, and ease of installation.
