Speciality He-Ne Laser 0.5 mW / Class II
Helium-Neon laser in a small-form-factor package for presentations and general-purpose optical use

The ML 800 series of lasers is a tried and true laser design originally designed and manufactured by Metrologic. We are very proud at Industrial Fiber Optics to continue producing this outstanding line of lasers, incorporating our own improvements. Designed with a sturdy metal enclosure and along the lines of classic laser design with integrated power supply this laser is an excellent choice for an industrial or educational application.

The versatile Class II ML 811 is one of the smallest educational and laboratory lasers made today. Its small size makes it easy to hold in one hand, yet it has excellent beam quality and frequency stability, just like full-size lab lasers. Laser includes 110-VA- to-24-VDC power adapter and safety warranty information.

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.
