3 Reasons Cause Laser Pointer not Burn

In various high tech and entertainment working fields, laser pointers are always widely used in every corner of the world. Someone might use a laser pointer without any problem more than 2 years. However, laser pointer might also burn out after very short term. Besides self problems of laser pointer, it is also very important to make proper operation of this laser gadget.

1. laser pointer cannot be lighted up.

In formal laser pointer operation work, it might stop work. Before it needs repairing from laser manufacturer, we might also check possible reasons as below:

a. improper operation of laser pointer. Longer time continuous pointing of laser pointer might cause serious hot and temperature increasing of laser tube. It can easily cause burning out of laser module.
Users would have to change laser module.
b. throw or touch cause damage of laser pointer.
Laser pointer is fragile product comparing with others. Improper using such as throwing might cause collision damage of modular structure. Laser pointer might not be able to point normal light.
c. battery installed backwards. Lack of special attention, occasional battery installed anti might cause laser pointer burn out.
d. product itself structure problem. Poor crystal quality and unstable electric circuit design can cause laser pointer problem.

2. Laser light expanding

Sometimes laser pointers might be use in improper occasions, such as current poor air quality, the lens of laser pointers always require high level of cleanliness requirement. If lens glue dust, the laser light is scattered, not concentrating. Beam range of laser pointer becomes closer as well.

3. Green laser pointer gets two light spots. (crystal division)

a. low operating temperature, laser pointer is not completely excited to start, appears two spots. As the temperature rises, laser spot gets better.
b. unstable crystal structure.
the latter two issues are small problems, users only need to clean and replace laser module.

The most serious is not lit, the module completely burn out, users would have to pay the cost of the replacement module.
Whenever users are selecting laser pointers, it is very important to get genuine laser with reliable warranty. Whatever kind of problem exits during the use of laser pointers, laser operators can always get the most satisfied resolution within guaranteed period.
