Laser Pointer - Regulations and Misuse - Netherlands
... Before 1998 Class 3A lasers were allowed ... In 1998 it became illegal to trade Class 2 laser pointers that are "gadgets" (e.g ... It is still allowed to trade Class 2 (< 1 mW) laser pointers proper, but they have to meet requirements regarding warnings and instructions for safe ...
Hazards - Infrared Hazards of DPSS Laser Pointers
... Lasers classified as pointers are intended to have outputs less than 5 mW total power (Class 3R) ... At such power levels, an IR filter for a DPSS laser may not be required as the infrared (IR) output is relatively low and the brightness of the visible wavelength of the laser will cause the ... However, higher-powered (> 5 mW) DPSS-type laser pointers have recently become available, usually through sources that do not follow laser safety regulations for laser packaging and labeling ...
Laser Pointer - Regulations and Misuse
... Since laser pointers became readily available, they have been misused, leading to the development of laws and regulations specifically addressing use of such lasers ... Their very long range makes it difficult to find the source of a laser spot ... as they are indistinguishable from dot type laser reticles ...
Laser Pointer
... A laser pointer or laser pen is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-pow ... The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, only 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 droplets along the beam path ...
