Features of Laser Pen
The laser pen is typically a class 2/3 laser powered by AAA batteries. It has a fixed focus, a low-divergence angle, and an output power of 1-200mW. Pen-shaped lasers are usually cheaper than flashlight-shaped lasers and are easier to use (ideal for beginners).
Laser pens have different applications in different power ranges. For astronomical use, 10-200mW is recommended. For presentations, a lower power of 1-10mW is more appropriate and safe. For other applications, you can contact us to get the most suitable laser pen.
