Features

Direct Green Laser Diode for large temperature operation range. Line-width at the distance of 10 meters(32.81ft.) is less than 3.5mm(0.1378 in.). Laser line accuracy: 40" (+/- 1mm @5m). Operating Voltage: 7~10 VDC. Dimensions: D0.492 x 1.181 inches (D12.5 x 30 mm).
Wave length: 520nm. Laser power output: Class II – less than 1mW. (Update 03/21/2020 - 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 IIIa" to "Class II" now, even though the brightness is exactly the same as before.)
