Blue-violet lasers target emerging technologies

Photonic Products has added 405nm (blue-violet) laser diode modules to its range of photon laser modules.

Designed as a complete laser diode system for OEMs, the 405nm laser modules are suitable for use in applications such as biomedical instrumentation, imaging, spectroscopy, fluorescence sensing, microscopy and many other emerging technologies.

The compact and efficient 405nm laser modules 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 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.

The laser is extremely stable and reliable and offers the added advantage of TTL modulation input which will accept signals from DC up to 1 kHz minimum.

TTL modulation can be used to enable, inhibit or modulate the laser.

Operating voltage is from 6.5V to 12V DC at an operating current of 90mA, or 100mA.

Beam divergence is less than 0.6mrad for the circular output beam and better than 0.6 x 0.3mrad for the elliptical output beam.

Operating temperature range is -10 to +50C.

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 12mm diameter by 43mm length.

Electrical connections are made via external flying leads.
