class iiib laser Laser Safety

Class I lasers are low powered devices that are considered safe from all potential hazards. Some examples of Class I laser use are: laser printers, CD players, CD ROM devices, geological survey equipment and laboratory analytical equipment. No individual, regardless of exposure conditions to the eyes or skin, would be expected to be injured by a Class I laser. No safety requirements are needed to use Class I laser devices.

Class II lasers are low power (< 1mW), visible light lasers that could possibly cause damage to a person's eyes. Some examples of Class II laser use are: classroom demonstrations, laser pointers, aiming devices and range finding equipment. If class II laser beams are directly viewed for long periods of time (i.e. > 15 minutes) damage to the eyes could result. Avoid looking into a Class II laser beam or pointing a Class II laser beam into another person's eyes. Avoid viewing Class II laser beams with telescopic devices. Realize that the bright light of a Class II laser beam into your eyes will cause a normal reaction to look away or close your eyes. This response is expected to protect you from Class II laser damage to the eyes.

Class IIIa lasers are continuous wave, intermediate power (1-5 mW) devices. Some examples of Class IIIa laser uses are the same as Class II lasers with the most popular uses being laser pointers and laser scanners. Direct viewing of the Class IIIa laser beam could be hazardous to the eyes. Do not view the Class IIIa laser beam directly. Do not point a Class IIIa laser beam into another persons eyes. Do not view a Class IIIa laser beam with telescopic devices; this amplifies the problem.

Class IIIb lasers are intermediate power (c.w. 5-500 mW or pulsed 10 J/cm²) devices. Some examples of Class IIIb laser uses are spectrometry, stereolithography, and entertainment light shows. Direct viewing of the Class IIIb laser beam is hazardous to the eye and diffuse reflections of the beam can also be hazardous to the eye. Do not view the Class IIIb laser beam directly. Do not view a Class IIIb laser beam with telescopic devices; this amplifies the problem. Whenever occupying a laser controlled area, wear the proper eye protection. Refer to the University of Kentucky Laser Safety Manual for complete instructions on the safety requirements for Class IIIb laser use.

Burning Lasers

The burning lasers are the laser that burning. If someone wants to buy burning laser, that means he wants to buy burning laser pointer. Most of the burning laser for sale are burning laser pointers.The burning laser pointer for sale are burning green laser pointer,red burning laser pointer and burning blue laser pointers. The burning green laser pointers have a power of 200mW, while red burning laser pointer is 100mW red laser pointer. Many of the burning laser for sale are focus-adjustable. All kinds of burning laser pointer for sale at BeamQ burning lasers.

Cheap Laser Pointers

Some laser enthusiasts want cheap laser pointers, including cheap green laser pointer,cheap blue laser pointer,cheap burning laser. The cheap laser pointers cost you less, but many of the cheap laser pointers are not real cheap, as their power may be much lower than it claimed.

1w blue laser (1 watt blue laser)

More aboout  1w blue laser pointer

1w blue laser (1 watt blue laser) is the portable laser or laser module with blue laser 1w. Most of the 1w blue laser for sale are 1w 445nm laser. 1w blue lasers are 473nm 1w blue laser, or 445nm 1w blue laser. The 445nm blue is very similar to 473nm blue. BeamQ 445nm 1000mw super strong focusable blue laser pointer flashlight is the cheapest 1 watt blue laser

Invisible lase

When we say invisible laser, it means invisible infrared laser. The infrared laser pointers may be 808nm laser pointer or 980nm laser pointer. Some laser enthusiasts name the invisible laser to black laser pointer, as the invisible laser can't be seen, but it is there! The laser 808 nm illuminator is made by 808 nm laser module. There are many types of 808 nm laser modules, and some of the 808nm laser modules work seperately, they won't be 808nm laser pointer. The 2w 808nm handheld laser is 808nm free shipping here at Armlaser, as the 2w 808nm handheld laser is Armlaser promoted products.

1W laser ( 1Watt laser )

1W laser ( 1Watt laser )

When we say 1w laser or 1watt laser, usually it's a 1000 mw laser pointer that emit laser 1w. 1w laser pointer (1000 watt laser pointer) may be 1watt laser green, 1watt laser blue (445nm blue) or 1watt laser infrared. Most of the laser 1w are used at labs and science. 1000 mw laser pointer can't be used as target or pointing purpose. 1watt laser (1000 watt laser) is extremely dangerous for human eyes or skins. 1 w laser will burn skins or blind people. 1 watt laser blue or 1 watt laser green will be blocked by the same 1 w laser goggles, as the 532nm and 445nm 1w laser wavelength are at the same section for the laser protection goggles.

2W Laser Pointer

The 2000mw laser torch has an artistic and delicate appearance. The cabinet dimension is fit for holding in hand comfortably. The Torch is colored with an anode-oxidized technique in different colors, such as black and green ,etc. It is abrasion resistant ，never fading in color. Advanced IC chips are applied on the power source, so it has a high efficiency and provide low heat. Besides it has a broad tension, which insures a constant current without decreasing the power of the beam when the voltage ranges from 2.9 V to 4.2 V，extending the durability of the battery effectively. The LD pedestal is measured accurately with the thermal resistor. It can switch off the power automatically once the temperature limit is exceeded, and thus the laser can be protected efficiently.
