Diode Laser 0.8 mW / Class II
A hand-size laser capable of transmitting NTSC color video

The ML268 is one of the most popular lasers in our product line and remains unique today as when introduced 15 years ago. It incorporates the best features of full- or lab-sized lasers in a convenient hand-size design only slightly larger than conventional pen-sized laser pointers. The laser is suitable for use in lectures and A/V shows, transmitting video pictures over a laser beam, or as a lab laser for optical experimentation and demonstration. (Metrologic Instruments produced this laser until 2004. IFO redesigned it and now manufactures an improved version.)

It is the smallest Class II hand-size laser we manufacture with a visible semiconductor laser diode technology. It is readily portable and applies to a wide range of educational applications.

The ML268 operates directly from a 110-VAC-to-9 VDC power adapter/charger, or from internal rechargeable batteries. When fully charged the batteries typically provide two hours of continuous operation. The optical beam can be electrically modulated via a standard audio RCA-type jack. The internal circuitry is electrically compatible with NTSC color video signals from a camcorder or VCR, or audio signals from low-impedance sources.* Its solid-state visible laser diode and miniaturized electronic components make this the smallest modulated educational laser on the market. A decade and a half since its introduction, this laser pointer remains an innovative product with outstanding performance.

Laser includes 115-to-9 volt power adapter and full-color operators manual.

* With an additional amplifier circuit to amplify/buffer high-impedance audio sources, the ML 268 can also be used to create an optical audio transmission link.

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.
