Blue-violet laser diode modules

Photonic Products Ltd. in Hatfield Broad Oak, England, is offering 405-nanometer blue-violet laser diode modules for applications such as imaging, fluorescence sensing, spectroscopy, microscopy, and biomedical imaging. The modules produce either an elliptical output beam of 4-by-1.5 millimeter with output of 4 milliwatts, or a 2-millimeter circular output beam with output power of 0.9 milliwatts. The glass AR-coated optical lens adjusts to produce a collimated beam or focused spot. Operating voltage is from 8 to 12 volts DC at an operating current of 90 milliamps, or 100 milliamps.
