Dimensions: D9 x 26 mm. Connection type : Lead wire. Please notice: laser modules are not supposed to be sold with any power source, power supply, base for plugging, or wiring terminals. Because modules are simply components, and it means that you have to wire it to your own power source by yourself.

Wave length: 645~665 nm. Laser power output: Class I – less than 0.39mW. (Update 04/13/2021- According to the latest IEC 60825-1 regulations, the output is measured by 7mm aperature stop at the position of 10cm. Therefore, its Class is changed from "Class II" to "Class I" now, but the brightness is exactly the same as before.)

High accuracy Red Straight Line Laser, for Industrial high-precision leveling, alignment, adjusting, positioning, measuring and targeting device.

Wave length: 635nm. Laser power output : Class I – less than 0.39mW. (Update 03/19/2021 - The laser output (the brightness) is exactly the same as before. The reason why the Laser Class is changed now is that, according to the latest IEC 60825-1 regulations, the output is measured by 7mm aperature stop at the position of 10cm. Therefore, you see that its Class is changed from "Class II" to "Class I" now, even though the brightness is exactly the same as before.)
