Laser Pointer Problems in Winter

When laser pointer is in formal work, it always requires certain operating environment. Generally its acceptable operating temperature is range from 10 degree to 40 degree Celsius. Some special laser pointers might be workable under operation temperature with range level of 0-40 degree Celsius, or even lower operating temperature.

In winter with low working environments, laser beam emission is always very weak, dim and not bright at the very beginning of starting up. After continuous pointing, usually after 10 seconds, laser beam brightness recovers to normal value. For instance, a APC green laser pointer gets the best performance under 25 degree Celsius. When operating temperature is quite lower, laser operators should make preheating of laser pointer. Low temperature might greatly affect formal working of laser pointers.

Especially below zero temperature, the laser pointer light might appear weak, and or not even able to start. In winter, laser users should pay special attention to surrounding environment, so as to assure formal operation of laser pointers.

When operating temperature of laser pointer is quite lower than expected, it is very important to make preheating of laser tube. Especially head part of laser pointer, should be preheated inside coat, or hands. If laser pointer starts up in room working environment, it will recover to formal or near formal working environment.

Sometimes there is heavy fog in winter, laser pointer operators should also pay special attention to operating environment. Users should prevent dust of fog attached to the lens of laser pointers, affecting the quality of the laser spot, thus indirectly affect the beam thermal efficiency.

Caution with laser pointers operation

Whenever users are pointing any powered laser pointers, it should be not pointed continuously. The extremely high temperature of laser tube might cause burning out of internal laser crystal and laser diode. The recommended operation time of laser pointer should be 30 seconds pointing, and then 10 seconds cooling down.

Laser users should always obey proper operation measures of laser pointers. It is not allowed to point laser pointer in public, animal and human eyes and body, moving vehicles, air planes etc.

When the selecting output power of laser pointer is higher than 30mW, users should remember to wear laser safety goggles in order to make perfect protection of eyes. Never try to stare at laser radiation and laser reflection. Any explosion of laser beam might cause serious hurt to eyes and retina seriously.
