The beam emissions of Global Laser products meet the the requirements of IEC classifications listed below between classifications 1 and 3B. However since the majority of products are supplied as OEM components we have no control over the accessibility, number of lasers used, exposure, operating times etc.. and therefore we generally do not IEC classify the item itself.
Laser Class 1
A Class 1 laser is safe for use under all reasonably-anticipated conditions of use; in other words, it is not expected that the maximum permissible exposure (MPE) can be exceeded.
Laser Class 1M
Class 1M lasers produce large-diameter beams, or beams that are divergent. The MPE for a Class 1M laser cannot normally be exceeded unless focusing or imaging optics are used to narrow down the beam. If the beam is refocused, the hazard of Class 1M lasers may be increased and the product class may be changed.
Laser Class 2
A Class 2 laser emits in the visible region. It is presumed that the human blink reflex will be sufficient to prevent damaging exposure, although prolonged viewing may be dangerous.
Laser Class 2M
A Class 2M laser emits in the visible region in the form of a large diameter or divergent beam. It is presumed that the human blink reflex will be sufficient to prevent damaging exposure, but if the beam is focused down, damaging levels of radiation may be reached and may lead to a reclassification of the laser.
Laser Class 3R
A Class 3R laser is a continuous wave laser which may produce up to five times the emission limit for Class 1 or Class 2 lasers. Although the MPE can be exceeded, the risk of injury is low. The laser can produce no more than 5 mW in the visible region. Examples of Class 3R products include some laser pointers and some alignment products used for home improvement work.
Laser Class 3B
A Class 3B laser produces light of an intensity such that the MPE for eye exposure may be exceeded and direct viewing of the beam is potentially serious. Diffuse radiation (i.e., that which is scattered from a diffusing surface) should not be hazardous. CW emission from such lasers at wavelengths above 315nm must not exceed 0.5 watts.
Before you install the laser diode module into your equipment, make sure that:
1. Serial number of your product corresponds to the number in the packing list.
2. Supply voltage and laser diode module control signal correspond to those set by yourself.
