Light Ray Viewing Project w laser .5 Class II
Project for easy viewing of light rays

The Light Ray Viewing Kit is a small "liquid laboratory." When used with any of our lasers it creates underwater light ray patterns and diagrams that constitute the basics of all introductory optic studies. In a complementary series of activities in the accompanying instruction guide, students can observe, and more readily understand, principles and equations such as:

  • Snell's Law
  • Total internal reflection
  • Equal angles of incidence and reflection
  • Critical angle of light

Set-up for each experiment requires less than five minutes and costs only a few pennies. ("Just add water!")

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.
