Laser pointer with fixed focal length
This laser pointer has a fixed focal length and uses an 18650 capacity battery, so there's no need to worry about the battery life of these lights. At the same time, the laser light source has high brightness and long service life, which greatly reduces the maintenance cost of the latter. At the same time, the laser projector starts almost instantly and reaches the working brightness in an instant, so the laser projector is considered to be a kind of fast switch machine. Aiming at an aircraft with a laser pointer is not only illegal, it is also extremely dangerous for the pilot of the aircraft. Even if you're sure you're pointing at a star, it's better to circle the object with the high power laser pointer instead of pointing at it. Powered by battery. As a result, red light gradually forms, which is greatly amplified by being reflected again and again between the two mirrors. On the front end, at the touch of a button, the desired red laser appears, which is only one wavelength, strong beam and high intensity compared to incandescent light.

Therefore, green laser pointers ranging from 5mW to 150mW are widely used in astronomy, and the laser pointer in our work uses 532nm. You can focus the beam on that point by turning the wheel. It has six modes: low, medium, high, strobe, SOS, and of course, off. I like that it's waterproof and has an extra seal. Apparently well done. Since the power output is greater than 1mw or less, this 5mw red/green laser pointer can be used in many places: pointing, cat teasing, fun, camping, etc. Powered by battery. As a result, red light gradually forms, which is greatly amplified by being reflected again and again between the two mirrors. On the front end, at the touch of a button, the desired green laser pointer appears, which is only one wavelength, strong beam and high intensity compared to incandescent light. When a high-power green laser pointer is attached to the telescope, the bright beam of the green laser will easily help astronomers target objects quickly and easily.
