Introduction and Application

A laser pointer or laser pen is a portable and visible laser. It is designed to highlight something of interest by projecting a small bright spot of colored light onto it. The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, showing a point of light when striking an opaque surface. Some higher-powered laser pointers project a visible beam via scattering from dust particles or water/fog droplets along the beam path. Higher power and higher frequency lasers may have a visible beam even in clean air due to Rayleigh scattering from air molecules, especially when viewed in moderately-to-dimly lit conditions. The intensity of such scattering increases when these beams are viewed from angles near the beam axis. Such pointers, particularly in the green-light output range, are used as astronomical-object pointers for teaching purposes, in the same general manner as flashlights.

NOTE from Ankaka Sale Department:

• Never point at people and always avoid direct eye contact. Please keep out of reach of children
• This pointer is not designed for long-term use. Constantly turning on will result in accumulation of high temperature and sacrifice the lifetime of laser diode
• In some countries these laser pointers (especially the higher powered ones) may be illegal to own and/or use. Therefore, by purchasing
• These products you (the customer) accept all responsibly and liability to determine and fulfill the requirements and limitations of use or resale of these products in accordance with your country's laws and regulations.
