Different types of laser pointer can show different colors of light, and the apparent brightness of a spot from a laser beam depends not only on the optical power of the laser and the reflectivity of the surface, but also on the chromatic response of the human eye. The laser pointer can be used to highlight something of interest by projecting a small bright spot of colored light onto it. It can be used in different areas which include educational and business presentations, architecture, astronomy, camp and adventure, and entertainment etc. Just Remove Disco Light Effect Cap From Pen To Get Straight Pointer Light For Presentation. it is lightweight and handy, easy to carry and suitable for put in your pocket or handbags.
