Beam divergence of 520nm laser
Although many astronomers and hobbyists use high-power lasers, such as handheld devices or laptops, it is not actually necessary. A dual-power laser designator like ours (5-80MW) is sufficient. The reason many people still use high-power lasers is the visibility of the beam. So if you decide to use lasers that are more powerful than green laser pointer, be sure to take extra safety precautions and make sure everyone around you wears safety glasses. In addition to being temperature insensitive, the 520nm green laser is more robust than the 532nm used. Our 520nm lasers can withstand turbulence and are less likely to fail due to internal failures.

In addition, you will find that our 520nm lasers have much less beam divergence because they are not crystal-based. Thanks to our components, your beams will be stronger, travel farther and provide more reliable performance. There is a reason for laser and lighting professionals to drop from 532 to 520. Professionals in the lighting, astronomy and metrology industries are raving about the benefits of the high-power 520 laser. In the design of laser beam extender, the objective lens and the image lens are opposite. In the Kepler beam extender model, the collimating input beam is focused at a point between the objective lens and the image lens, producing a point in the system where the high powered laser energy is concentrated. The focus heats the air between the lenses, deflecting light from its path, which causes wavefront errors. For this purpose, most beam extenders use the Galileo beam extender design or its variants.
