An economical range of compact, 8mm diameter, laser diode modules for integration into laser systems and handheld instrumentation where space is at a premium.

Typical applications are targeting, industrial alignment such as pre-press plate alignment, laser alignment for label and wrapper cutting machinery and medical alignment applications such as patient positioning.

The laser modules measure just 25.5mm in length, with a diameter of only 8mm and are extremely efficient and reliable at an economical price.

The 650nm laser diode modules produce an elliptical, collimated output beam of 3.5 x 1.5mm, with output powers of 0.9mW or 4.5mW. The 635nm laser diode modules produce an elliptical, collimated output beam of 3.5 x 1.5mm, with output powers of 0.9mW or 4.0mW. Operating voltage is from 3V to 6V DC at an operating current of 30mA typ, (0.9mW) or 40mA typ, (4.5mW). Beam divergence is less than 1mrad and operating temperature range is -10 degrees Centigrade to +50 degrees Centigrade at 650nm and -10 degrees Centigrade to +40 degrees Centigrade at 635nm.

The laser modules consist of a brass housing, laser diode, drive circuit and adjustable collimating or focusing lens. The lens may be adjusted to produce either a collimated beam or focused spot. Electrical connections are made via external flying leads. They have been designed as a complete and affordable laser diode solution for OEM companies.

For applications requiring electrical isolation of the laser module housing, a hard anodised aluminium housing version of this compact laser module is available.
