Photonic Products has launched a 660nm laser diode module with a very high, very stable output power of 70mW and adjustable AR coated glass optics.

The 660nm Photon Laser Module, PM806G-GR, incorporates an Opnext HL6548FG high power laser diode (100mW absolute maximum optical output power), with internal monitor photodiode in a 9mm package. An internal monitor photodiode is a unique feature for a laser diode of this power and wavelength, which enables the output power of the laser diode module to be accurately stabilised over its operating temperature range of -10°C to +50°C.

Designed for applications such as machine vision, graphic displays, medical imaging, inspection systems, and industrial alignment and positioning, the 660nm laser diode module produces an elliptical output beam of 3.5 x 1.5mm with an output power of 70mW. Operating voltage is from 3V to 6V DC with a typical operating current of 150mA. Beam divergence is <0.6 x 0.3mrad and operating temperature range is -10°C to +50° C. The module consists of an aluminium housing, laser diode, drive circuit and collimating lens and is stable and reliable.

All photon modules can be supplied in various colours, (red, green, blue, black, violet), to assist in wavelength or power identification. The PMF version modules have a 25mm mounting flange. Electrical connections are made via external flying leads. The lens may be adjusted to produce either a collimated beam or focused spot. The standard lens may be replaced by other optical systems such as line and cross generators.
