Diode Laser Kit 0.8 mW / Class II
A "build it yourself" lab laser that can be completed in as little as 3 hours

For more adventurous electronics hobbyists, IFor more adventurous electronics hobbyists, Industrial Fiber Optics now offers a kit version of our highly successful lab size (semi-conductor) diode laser line. With electrical and optic specifications similar to our IF RL08 635, you can now have the additional enjoyment and challenge of being able to build it from the component level up. An ideal project for student laboratory use, classroom demonstrations, laser shows and science projects.

Once assembled, this laser produces a highly collimated beam of 635 nm red laser light. It is also the only laser on the market which includes an internally-adjustable, internal electronic amplifier with a variable gain from 1 to 50 making it suitable for low-voltage microphone inputs as well as higher amplitude signals from AM/FM radios and CD/tape players.

Kit contains printed wiring board, electronic components, switches, laser diode, laser diode mount, collimating lens, impact-resistant acrylic enclosure with end cap, beam shutter, CDRH labels, power adapter and step-by-step assembly guide, circuit schematic and parts list. Does not include soldering iron or solder. (We recommend some soldering experience and understanding of simple schematics to complete this project.)

Assembly requires 25-watt soldering iron, electronic solder, screw driver, needle nose pliers and wire cutter.

LASER CLASSIFICATIONS

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.
