4.5V laser head, laser module, laser tube, laser diode, plastic gyro module, red dot

Product composition: laser head emitting die consists of three parts, a condenser lens, delivered to the user when the sleeve is composed of three parts has been assembled, but also adjust the focal length of the lens and has a good strong glue stick, the user connect DC 4.5V The power supply can work.

Product description: Under ideal conditions (no dust, no smoke, no obstructions), the transmission distance of the laser is unlimited. This laser head in the case of higher air quality when operating current to 20MA, the transmission distance can reach 1KM above, in the night cloudy general, casually irradiated to the object than 500 m supernatant clarity visible; For close At distance, even in the daytime sun, it is clearly visible on outdoor roads and buildings.

Working voltage: 4.5V 51 resistance Working time: quite long (because there is no accurate test)
