The LQB-0.4S-670 from World Star Tech is a Single Mode Red Laser Module with an output wavelength of 670 nm. It delivers a CW output power of 0.4 mW and has a stability of 1 %. The laser produces a collimated beam that has a spot size of 3 mm and a divergence at the collimation of 2 mrad.
The LQB-0.4S-670 requires a DC supply of 3-5 V and consumes up to 50 mA of current. It has integrated auto power control circuitry that offers reverse polarity protection. The laser is available in a module that measures 9 x 19 mm with a 380 mm long cable and is ideal for targeting, automation, and alignment applications.
Note: This laser module has an IEC certification of Class 1 and a CDRH certification of Class II; direct exposure to its radiation is harmful to the human eye.
