Laser Diodes

Sanyo, Union Optronics and eGismos provide industrial laser diodes from 405nm-445nm blue-violet (InGaAs), 635nm-670nm red (AlGaInP), up to 850nm-980nm infra-red (AlGaAs). Shimadzu and eGismos also produce green laser modules (532nm), using pumped output from an infra-red laser diode.
Most laser diodes come in 5.6mm case size, but some specialist ones are available in 3.8mm and 9mm cases. Many of these laser diodes contain a monitor photodiode which allows for the output power to be kept at the correct level by adjusting the voltage.
There are many uses for Sanyo, U.O.C., Shimadzu and eGismos laser diodes and modules, anything from optical disk drives (BluRay) and laser pointers, to barcode readers and medical skin care.

Laser Safety

The light emitted from these devices has been set according to IEC60825. However, staring into the beam, whether directly or indirectly, must be avoided. IEC60825 classifies laser products into three different catagories depending on light emitted, wavelength, and eye safety.

Class II

Caution - visible laser light less than 1.0mW. Considered eye safe; normal exposure to this type of beam will not cause permanent damage to the retina.

Class IIIR

Danger - visible laser light between 1.0mW and 5.0mW. Considered eye safe with caution; focusing of this light into the eye could cause permanent damage to the retina.

Class IIIB

Danger - infrared (IR), and high power visible laser light greater than 5.0mW. Considered dangerous to the eye; any exposure will cause permanent damage to the retina.

N.B. It is important to note that while complying with these classifications that, unless otherwise stated, our laser diode products are not certified and are designed solely for OEM use. The way in which the device is used in the final product may alter its original design classification. It is the responsibility of the OEM to ensure compliance with the relevant standards.
