Photonic Products is launching 35mW and 60mW versions of its 405nm (blue-violet) Photon laser diode modules with TTL modulation.

Suitable for use in power-hungry applications such as industrial and medical imaging and inspection, high-resolution printing and emerging technologies where precision and sensitivity are vital, the laser modules are aimed primarily at OEMs.

The extra output power offered by these laser modules also provides higher energy density and greater accuracy and sensitivity for biomedical and biochemical analysis applications such as flow cytometry and laser-induced fluorescence sensing.

Designed to be extremely stable and reliable, the 405nm Photon laser modules produce an elliptical output beam of 3.5 x 2mm with the added advantage of a TTL modulation input that accepts signals from DC up to 1 kHz maximum and can be used to enable, inhibit or modulate the laser.

The glass AR coated aspherical 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 generators.

Operating voltage is from 8-10V DC. Beam divergence is typically <0.6 x 0.3mrad. Operating temperature range is -10 to +50 degrees C.

The modules are cylindrical with an optional 25mm mounting flange and consist of an aluminium housing, laser diode, drive circuit and collimating lens. They measure just 12mm diameter x 43mm long. Electrical connections are made via external flying leads.
