Laser Output


	Laser Wavelength:
	Your choices are...
	Violet		The laser has output corresponding to the violet region of the spectrum. Violet is considered the wavelength range from 390 nm to 455 nm.
	Blue		The laser has output corresponding to the blue region of the spectrum. Blue is considered the wavelength range from 455 nm to 492 nm.
	Green		The laser has output corresponding to the green region of the spectrum. Green is considered the wavelength range from 492 nm to 577 nm.
	Yellow		The laser has output corresponding to the yellow region of the spectrum. Yellow is considered the wavelength range from 577 nm to 597 nm.
	Orange		The laser has output corresponding to the orange region of the spectrum. Orange is considered the wavelength range from 597 nm to 622 nm.
	Red		The laser has output corresponding to the red region of the spectrum. Red is considered the wavelength range from 622 nm to 780 nm.
	Other		Other unlisted or specialized wavelengths.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Laser Performance


	Laser Power		Laser power is measured in watts (W) and indicates the strength of a laser beam. A watt is one joule of energy per second.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Beam Area		Beam area refers to the area of the beam when exiting the laser.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Laser Weight		The weight of the laser and power supply.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

CDRH Classification The Center for Devices and Radiological Health (CDRH), a part of the U.S. Food and Drug Administration (FDA), has a laser safety classification scheme.



	Your choices are...
	Class I		Class I lasers are not hazardous for continuous viewing, or are designed to prevent human access to laser radiation. Class I lasers include both low-power lasers and embedded, high-powered lasers. Applications include laser printers.
	Class II		Class II lasers emit visible light which, because of the normal human aversion response, does not normally present a hazard. If viewed directly for extended periods of time, however, Class II lasers can cause eye injuries.
	Class IIa		Class IIa lasers emit visible light that is not intended for viewing, and that under normal operating conditions will not injure the eye if viewed for less than 1000 seconds. Barcode scanners use Class IIa lasers.
	Class IIIa		Class IIIa lasers will not normally injure the eye if viewed momentarily, but present a hazard if viewed using collecting optics.
	Class IIIb		Class IIIb lasers present an eye and skin hazard if viewed directly. This includes both intrabeam viewing and specular reflections. Class IIIb lasers do not produce a hazardous diffuse reflection except when viewed at close proximity.
	Class IV		Class IV lasers present an eye hazard from direct, specular and diffuse reflections. In addition, they may pose a fire hazard and burn skin.
	Other		Other unlisted CDRH classifications.
	Search Logic:		Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.
