33*55mm 650nm 660nm 200mW-250mW Red Dot Laser Module with Fan 12VDC Stage Lighting

Description33*55mm 650nm 660nm 200mW-250mW Red Dot Laser Module with Fan 12VDC Stage LightingProduct Description650nm 660nm Red 200mW-250mW Laser Diode Module 12VDC Stage LightingThis laser module is an industrial electronic component and used for as Industrial test, Lab, DIY. Comparing with 532nm green or 650nm red lasers, 405nm/450nm violet/blue laser is hard to be seen by human since the wavelength is on the range of spectrum by human eye sensibility. Not a handheld laser. We highly suggest that you use good cooling for laser driver if you use it long time. Specification Output Power:250mW Wavelength: 660nm Working Voltage: 12VDC TTL: N/A Laser Shape: Dot (Ellipse) Material: Metal Lens: Glass Working Voltage: 12VDC Dimension: 33X33X55mmNote: The modules are tested and the output power are measured by laser power meter before sending out. Please don’t compare the power of this one with a none-measured laser. If you doubt the output, please have the laser you recieved checked by laser power meter. If there is any problem, please feel free to contact us. We will solve the problem asap. Fan is temp control. so that it may not always turns on.
