Light Amplification by Stimulated Emission of Radiation

• LEVEL - A Horizontal Laser Reference Plane perpendicular to gravity
• PLUMB - A Vertical Laser Reference Plane parallel to gravity
• LASER DIODE - Laser Light Producing Electronic Device
• NANOMETER - Wavelength Of Light Emitted By A Laser Diode (i.e. 635nm)
• ACCURACY  - Tolerance Of The Laser Beam At A Distance From The Tool (i.e. ± 1/4" per 100')
• MILIWATT - A Measurement Of Laser Light Power (5mw)
• VISIBLE RANGE - Distance Away From The Laser Level You Can Still See The Beam (100')
• MANUALLY LEVELED - User Levels The Tool With The Aid Of Bubble Vials
• SELF-LEVELING / AUTO-LEVEL - Laser Levels Itself either Electronically or by using Gravity
• CALIBRATION - Procedure For bringing the accuracy of the laser to within it's spec
• CLASS II LASER PRODUCT - Regulatory designation for a laser product less than 1mW
• CLASS III LASER PRODUCT - Regulatory designation for a laser product less than 5mW
