He-Ne Laser Kit 0.5 mW / Class II
A "build it yourself" full size Helium-Neon Class II Laser

Industrial Fiber Optics invites you to build your own helium-neon laser. In this kit, you'll find all the components you need, including schematics and step-by-step instructions to assemble a full size helium neon laser. It can be assembled in just three to five hours. When completed this laser will have the same electrical and optical specifications as the ML 800 laser. Assembly of the laser also provides the satisfaction of building a laser from the ground up, and a better understanding of the inner workings of a helium neon laser. An ideal project for student laboratory use, classroom demonstrations, laser shows and science projects.

Kit comes complete with hard-seal helium-neon tube, printed circuit board, electrical components, switch, fuse, laser tube mounts, transformer, high-voltage electrical wire, 3-prong electrical line cable, durable extruded aluminum housing and metal end caps with powder coating, screws, CDRH laser labels, assembly instructions, schematic, parts list and operating instructions. Does not include soldering iron or solder.

Assembly requires 25-watt soldering iron, electronic solder, Phillips #1 & 2 screwdrivers, 2 mm Allen wrench, needle nose pliers and wire cutter. We recommend some experience soldering and assembling kits, or assistance from someone who has.

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.
