A small laser module capable of delivering up to a 0.99mW visible red 670nm wavelength beam from a low voltage. Suitable for a wide range of general laboratory and field applications. SpecificationsDimensions 10.5mm dia x 28mm L plusmn0.5mmBeam aperture 2.8mm diaWavelength670nmPower supply5VdcOperating current40mAOutput power0.7 - 0.99mWCAUTION This device generates a visible beam of red light that will not burn or cut. However it is moderately hazardous and should not be viewed by the naked eye on the same axis as the beam.N.B PCB 11.8 x 7.5mm both dimensions plusmn0.5mm protrudes from the back of the module. Care must be taken when handling this device.
