   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. 
   Infrared       The laser has an output which corresponds to the infrared (IR) portion of the electromagnetic spectrum. Infrared is the wavelength range from .78 μm to 1000 μm. 
   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.
   Wavelength Range       The wavelength(s) the laser produces. 
   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.
   Multi-Line Output       The laser output consists of two or more coherent wavelengths. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   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 Specification
   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.
   Beam Divergence       Beam divergence refers to the change in beam diameter as a function of distance from 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.
   Polarized Output       The laser output is polarized. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Fiber Pigtailed       Lasers have an optical-fiber pigtail that is aligned and attached precisely for optimum coupling efficiency. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Features
   Features       
   Your choices are...         
   Internal Power Supply       The power supply is built into laser's housing. 
   Thermoelectric Cooling       For better performance, the laser uses a thermoelectric cooler, a solid-state device which converts current into a temperature difference between two junctions. These thermoelectric junctions can be connected in series or in parallel to increase their overall temperature drop or power. 
   Array       Laser arrays contain multiple lasers.  
   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.

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.
