Wood processing. Metal processing. Stone processing. Textile industry. Food industry. Automotive industry. Medical science Why choose direct green laser module? Direct Green Lasers are direct-diode semiconductor lasers. The stability of the laser output is greatly improved. Most green laser modules on the market are DPSS (diode pumped solid state) laser modules. DPSS (Diode-Pumped Solid State) is a conventional laser module that emits an infrared laser diode with a wavelength of 808nm and turns it into green by crystal. This is actually a very inefficient way of producing a laser beam as there is significant power loss. For Direct Green Laser Module, the semiconductor laser itself emits directly. The stability of the laser output is greatly improved since there is no additional crystal. Thanks to their good efficiency, the temperature increase of the lasers during operation is minimized. A long lifetime and high reliability at continuous operation is guaranteed. Product Features Direct Green Laser Diode for large temperature operation range. Wave length: 520nm. Laser power output: Class I ? less than 0.39mW. (Update 05/01/2020- The laser output (the brightness) is exactly the same as before. 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.) Operating Voltage: 7~10 VDC. Dimensions: D9 x 26 mm ( D0.354 x 1.024 inches). 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. Direct Green Cross Laser Line Generator. Line-width optimize at short distance(15.75 inches; 40cm) for consumer grade Laser Cross-Line generator applications. This module has integrated wavy lens, collimating lens, laser diode, and APC driver circuit. APC driver circuit enables constant Laser output power. Includes patented solid brass structure for the best shock resistance and better heat transfer consideration. Aspherical Plastic Lens and Plastic Wavy Lens provides tight Cross-Line Laser. Emitting angle: 60. Notice: Laser modules are NOT laser pens. Laser modules are NOT supposed to be used for commercial use like normal laser pointers.
