Handheld Laser Instructions
Power Supply
We suggest customers to use fresh batteries or full charged rechargable batteires to supply a laser pens. This is because all kinds of batteries drops voltage after some use, a used battery maybe just supply 1.0V since the rating of the battery is 1.5V. A laser is built to be powered by 3 volts that means lower than 2.5V power supply will cause the laser can not give enough output power or it does not work.
Working Tempearture
All lasers are sensitive to temperature, and a laser generates heat by itself when it is working. If the heat inside a laser module can not be sent out in time, the temperature of the laser's body will be keeping on increased. A laser can not be working well when the temperature is too high or too low, the ideal working temperature for a laser is from 20 to 26 Celsius, the general temperature for a laser to be working is from 10 to 35 Celsius.
Heat Sink
Exteranl objects can help the heat sinking from the laser when it is working or transfer more heat to the laser if the external objects is at a higher temperature. The laser body/case of our lasers are ideally for heat transfering.
Laser Lens

A laser's lens is in the front the laser and covered by a front cap. It is always possible that the lens is dirty, a very tiny dust on the lens will cause the laser beam to be diffused. A laser lens is more sensitive than a camera's lens, It can be cleaned by professional person from a camera shop or cleaned with professional equipments.
