WBS Diode Lab Laser 0.8 mW / Class II
The ultimate educational communications laser

Industrial Fiber Optics was the first company to recognize the benefits, and develop a product line, of diode lasers for educational use. Today, we offer five models of lab-sized (semiconductor) diode lasers and one hand held model with rechargeable batteries. One of those models is the WBS Class II laser which is the ultimate product for demonstrating versatility of optical communications. This laser is also excellent for conducting general purpose optical experiments. (We do not recommend diode lasers for high quality interferometric experimentation or holography.)

Our diode lasers are unequaled to others by their many features such as high quality optics, well collimated laser beam, solid state electronics, great packaging, excellent operators manual and long warranty.

The WBS Laser produces a highly visible and well collimated beam of 635 nm red laser light. Electrical connections for the analog and digital inputs include industry-standard, durable banana jacks and 3.5 mm audio jack for audio/ microphone inputs. This laser is also the only product which includes an externally-adjustable, internal electronic amplifier with a variable gain from 1 to 50 making it suitable for low-voltage microphone inputs and higher amplitude signals from AM/FM radios and CD players.

Laser includes 110 VAC to 14 VDC power adapter and full-color operator's manual with common procedures and safety information.

All manufacturers of lasers used in the United States, must conform to regulations administered by the Center for Devices and Radiological Health (CDRH), a branch of the U.S. Department of Health and Human Services. CDRH categorizes lasers as follows:

 Class 1

A laser or laser system which does not present a hazard to skin or eyes for any wavelength or exposure time. Exposure varies with wavelength. For ultraviolet, .2 to .4m exposure is less than from .8 or near IR, the exposure is < 200w. Consult CDRH regulations for specific information.

 Class 2

Any visible laser with an output less than 1 mW of power. Warning label requirements yellow caution label stating maximum output of 1 mW. Generally used as classroom lab lasers, supermarket scanners and laser pointers.

 Class 3a

Any visible laser with an output over 1 mW of power with a maximum output of 5 mW of power. Warning label requirements red danger label stating maximum output of 5 mW. Also used as classroom lab lasers, in holography, laser pointers, leveling instruments, measuring devices and alignment equipment.

 Class 3b

Any laser with an output over 5 mW of power with a maximum output of 500 mW of power and all invisible lasers with an output up to 400 mW. Warning label requirements red danger label stating maximum output. These lasers also require a key switch for operation and a 3.5-second delay when the laser is turned on. Used in many of the same applications as the Class IIIa when more power is required.

 Class 4

Any laser with an output over 500 mW of power. Warning label requirements red danger label stating maximum output. These lasers are primarily used in industrial applications such as tooling, machining, cutting and welding. Most medical laser applications also require these high-powered lasers.
