Photonic Products, the UK opto-electronics device manufacturer and laser diode specialist, has introduced 405nm (blue-violet) laser diode modules with TTL modulation which have been designed as a complete OEM laser diode system.
The modules are extremely stable and reliable, ideal for use in medical applications such as biomedical instrumentation, imaging, spectroscopy, fluorescence sensing, microscopy and many other emerging technologies.
They produce either an elliptical output beam of 4 x 1.5mm with output power of 4mW, or a 2mm circular output beam with output power of 0.9mW.
The TTL modulation will accept signals from DC up to 1 kHz minimum and can be used to enable, inhibit or modulate the laser.
The glass AR coated optical 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 12V DC at an operating current of 90mA, or 100mA. Beam divergence is <0.6mrad for the circular output beam and <0.6 x 0.3mrad for the elliptical output beam. Operating temperature range is -10°C to +50°C.
The modules are cylindrical with an optional 25mm mounting flange and consist of an aluminium housing, laser diode, drive circuit and collimating lens. Mechanical dimensions are a compact 12 mm diameter x 43mm length. Electrical connections are made via external flying leads.
