Powerfully Blue-Violet Laser Modules
New from Photonic Products Ltd, the UK opto-electronic device manufacturer and laser diode specialist, are powerful 35mW and 60mW versions of its bestselling 405nm (blue-violet) Photon laser diode modules with TTL modulation.
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 TTL modulation input which will accept 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 8V to 10V D. Beam divergence is typically <0.6 x 0.3mrad. Operating temperature range is -10 to +50 degrees Centigrade. 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 a compact 12 mm diameter x 43mm length. Electrical connections are made via external flying leads.
