In current laser markets, red laser pointer and green laser pointers are always getting the longest development history. In addition, owing to the most visible and the brightest green laser beam emission to human eyes, green laser pointer always makes the best beam visibility at quite long working distance. As a result, besides common presentation in formal using fields, 532nm green laser pointer is also very popular to generate the most visible green laser beam at quite long working distance. As a result, this advanced laser pointer always gets wide application for astronomy stargazing, constellation observation, and celestial objects targeting etc.
Comparing with green laser pointer, red laser pointer gets less brightness and beam visibility than green laser pointer. However, this red laser just gets the longest development history. In those of formal presentation fields, it is always efficient enough to generate bright and visible enough red laser beam in all occasions. Unless it is being used under sunlight, this common red laser pointer is always workable for presentation fields such as school education, military targeting, lecturer, speech , exhibition etc.
Laser pointer is not the same as laser module. During the continuous laser beam presentation, it is very important to pay attention to general laser safety measures. After about 15 - 30 minutes continuous laser beam pointing, laser pointer should be power off until laser tube is fully cooling down. Only if users are obeying proper laser pointers safety rules, it will always play great work for all occasions efficiently.
