When the first time I operated 808nm infrared laser pointer, it is just very special and unique in use. Even though it has totally same structure as green, blue or red laser pointer, its infrared laser beam is always invisible in practical use. No matter how close it is targeted, users might found nothing but a dim and weak red dot on targeting surfaces. The red dot is very small and not easy to be found. Thus it has just brought users totally different applications in practical use.
In most of high tech applicable working fields, 808nm infrared laser pointer is always playing very important part in practical use. However, users should always be cautious enough with powerful laser radiation and laser reflections. In addition, users should take special attention to invisible IR laser beam since human eyes cannot feel and notices its beam emitting. Infrared laser pointer with longer wavelength can be easily reach human eyeballs and human body, thus it can easily hurt human skins and eyes temporarily. This near 808nm infrared laser pointer can hurt human retina directly.
When users are operating 808nm infrared laser pointer with any output power, users should always be cautious enough with powerful laser radiation and laser reflections. Users should always try to wear laser safety goggles to prevent any possible laser emitting. In addition, this infrared laser pointer should never be used as a toy, but a true laser tool applied in surveillance, military, and other high tech working fields only.
