Photonic Products Ltd announced that they are adding 405nm (blue-violet) laser diode modules to its range of Photon Laser Modules. Designed as a complete laser diode system for OEMs, this product is suitable for biomedical instrumentation, imaging, spectroscopy, fluorescence sensing, microscopy and 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, while the standard lens may be replaced by other optical systems such as line generators.

According to Photonic, their new laser is extremely stable and reliable and offers the added advantage of TTL modulation input which will accept signals from DC up to 1kHz minimum. TTL modulation can be used to enable, inhibit or modulate the laser, the company explained.

Operating voltage is from 6.5Vdc to 12Vdc at an operating current of 90mA or 100mA. Beam divergence is

The modules are cylindrical with an optional 25mm mounting flange and consist of an aluminum housing, laser diode, drive circuit and collimating lens. Mechanical dimensions are 12(?)-by-43(L)mm. Electrical connections are made via external flying leads.
