Description
In a lot of astronomy works, 5mW green laser pointer
is being used as a perfect presentation tool for a
lot of works, such as stargazing, constellation
observation and other celestial objects etc. The
operation of green laser pen is not the same as a
simple sticker. At night, green laser beam can be
extending as long as 2 kilometers into sky, after
very easy insert of 2 pieces of AAA batteries, green
laser pointer begins to work. Green laser beam is
clearly visible at night, thus it is making great
work to help astronomers to get very clear and
accurate targeting of all celestial objects.
When 5mW green laser pointer is used for astronomy
stargazing, it might be workable in various working
environments. Once the operating temperature is lower
than 25 degree Celsius, astronomers need to make
about 5 minutes preheating of laser pointer tube so
as to get highly bright and visible green laser in
distance. Once this astronomy green laser pointer is
not in use, the battery should be taken off, and put
in places where human hands cannot reach.
