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 of 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.
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.
Top 10 Problems of Laser Pointers
1. What is the difference between red laser and green laser?
Red laser gets wavelength of 635nm and 650nm, and green laser gets wavelength of 515nm, 520nm and 532nm. Different wavelength laser gets different color laser beam and light spot in operation.
Astronomy Laser Pointers
Astronomy lasers always chooses green laser pointer as its light source. 532nm green laser emits the most sensitive green color laser light, thus making the most visible and the brightest green laser beam radiation. This chosen astronomy laser pointer is always used for stargazing, constellation observation, and other celestial objects observation.
Laser Power and Laser Wavelength
Majority people are curious about how power a laser pointer can be, and relation between laser output power and wavelength. Which color laser pointer is the most powerful one with same range of output power? Even though with the same output power, different wavelength laser pointer would emit different power and energy.
Laser Pointers
Laser pointers are usually used as an eye-catching point in education, business presentation, and visual demonstrations.
1. Red laser pointer can be used in almost any indoor or low light situations, pointing out details by hand may be convenient.
2. Green laser pointer can be used for astronomy enthusiasts
