Standard Operating Procedures (SOPs) are required for all Class 3B and Class 4 lasers and laser systems (including imbedded lasers if hazards are accessible), and must be approved by the Laser Safety ...

When using a Class 3B or Class 4 laser, potential hazards from the direct beam exist to the eye and skin. The severity of these hazards is dependent upon the wavelength and the power output of the ...

The high power versions of the Patara lasers feature our modular and scalable DPSS technology for superior beam pointing, pulse to pulse stability, and high ...

The University requires that ALL Class 3R, 3B and 4 lasers are registered, risk assessed, and suitable control measures implemented. Heads of S/I/D are responsible for ensuring that all lasers within ...

DPGL series green lasers are diode pumped green lasers operating at 532nm. The diode, driver and optics are integrated in a compact package. The DPGL series lasers offer excellent beam quality and ...

According to the American Academy of Ophthalmology, laser lights with more than 5 MW power can damage the retina and ...

Dating as far back as the early 1960’s, researchers were zapping tattoo inks with laser light was an effective way to remove the markings from human skin. At the time it was prohibitively expensive.

Need a compact, capable projector you can take with you for presentations on the road—or just to tote outside for backyard ...
