He-Ne Lab Laser 1.5 mW / Class IIIa
High power He-Ne lab laser with modulation capability

Industrial Fiber Optics' CT Series of lasers are the most popular line of lasers used in middle and high schools in the United States. Designed for education, and featuring a bright blue transparent enclosure, their attractive looks invite students to participate and explore in optical and laser technology while seeing the laser's internal "working" components. With a complete set of features and long warranty, it is a product that is hard to surpass.

The IF HN15M is a unique laser created for the educational market. It has all the standard features and capabilities of a typical Class IIIa helium-neon laser, but it also includes additional electronic circuits for demonstrating voice/audio (data) transmission over the laser beam. (When used a suitable receiver to "decode" the light beam into an audio signal.) Audio signal can be either from any dynamic microphone or any audio device. See operators manual for information on microphone, electrical connections and set-up instructions. A great multi-function laser for doing basic laser, optical and data transmission demonstrations.

The CT Series lasers were designed for use in education. They are not an engineering product or design being sold for educational purposes. From the initial concept everything about the attractive, safe design was to interest students in technology. It includes safety features such as 110 VAC to low voltage power adapters, tamper-resistant screws, impact resistant acrylic enclosure, easily locatable bright red laser shutter, bright and very durable nickel-plated laser aperture, industry standard electrical connections and tripod mount.

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.
