FDA Accession No.:
The FDA is the United States Department of Health and Human Services. FDA imports use accession numbers to confirm that a manufacturer has followed the reporting requirements for the product being imported.
Laser Body:
The materials that make up the physical casing of the laser. The outer casing also serves as a heat sink for the laser module inside.
Laser Finish:
The final scratch-resistant finish applied to the laser casing.
Wavelength:
Visible light has a wavelength range of 400-700 nanometers (nm). Between lasers of equal output power (in mW), lasers closest to the peak visibility wavelength of 555nm will have more range and brightness than other wavelengths of laser light. Green lasers (532nm) are closest to the peak visibility wavelength (555nm), and therefore brighter than red, blue, and purple lasers. A laser's wavelength and power are two of the most important factors in choosing a laser. Please click here to learn about how different wavelengths correspond with relative brightness.
Transverse Mode:
In a laser with cylindrical symmetry, the transverse mode patterns are described by a combination of a Gaussian beam profile with a Laguerre polynomial. The modes are denoted TEMpl where p and l are integers labeling the radial and angular mode orders, respectively.
Max Power:
The maximum power level of the laser beam measured in milliwatts (mW). When choosing a laser a higher output power is brighter than a lower output power. For example, a 650nM @ 5mW laser is brighter than a 650nM @ 1mW laser.
Min Power:
The minimum power level of the laser beam measured in milliwatts (mW). When choosing a laser a higher output power is brighter than a lower output power. For example, a 650nM @ 5mW laser is brighter than a 650nM @ 1mW laser.
Beam Divergence:
A measure of how fast the beam expands as the distance from the source increases. The divergence is measured in milliradians (mrad). A low beam divergence is useful for applications like pointing or free-space optical communications.
Beam Shape:
The width of the laser beam @ aperture measured in millimeters.
NOHD
The Nominal Ocular Hazard Distance (NOHD) is the distance that a laser beam does not cause immediate or long term damage to a person. Calculated based on a 0.25 second accidental (unaided eye) exposure.
Beam Distance:
The maximum distance (in meters) at which the laser will produce 0.25 Lux of light. It's the standard that flashlights are measured against.
Required Eyewear O.D.:
Indicates whether or not laser protective eyewear is needed, and the necessary O.D. (optical density) of the eyewear for the laser wavelength being used. The indicated O.D. is the minimum O.D. sufficient to protect the user against a momentary intrabeam or specular reflection exposure.
Power Consumption:
The consumption of energy in the form of electricity. The average power consumption of an incandescent night light is 4W.
Power Supply:
The source by which the laser is powered.
Battery Lifetime:
The average amount of time the battery can last on a single charge.
Switch:
The switches that must be engaged to turn the laser on.
Mode:
The available laser beam modes once the laser is activated.
Duty Cycle:
The time cycle of which the laser can be active without causing damage to the laser module.
Expected Lifetime:
The average expected lifetime that the laser module can be in active use.
Warranty:
The time period for which any damaged or dysfunctional laser resulting from manufacturer's defects or workmanship will be replaced with a new product of the same model. Any attempted disassembly by a user will void the product warranty and may irreparably damage the product. We warrant all laser products sold on www.wickedlasers.com to be free of defects in material and workmanship.
