Coherent Inc. has introduced a new series of compact lasers that offer a combination of features to enable construction of space-limited point-of-care instruments for life sciences and diagnostic applications. The Coherent BioRay products are a line of diode lasers which include built-in collimating and focusing optics (to an elliptical beam), self-contained power supply and drive electronics and on-board modulation, communications and self-monitoring electronics. These lasers are available at five visible wavelengths (405 nm, 450 nm, 488 nm, 520 nm and 640 nm) with output powers as high as 50 mW. The lasers’ compact size, low heat output, small footprint and focusing optics make them easy to integrate into systems. Their excellent power stability minimizes the need for instrument recalibration, and their low noise output (less than 0.5% RMS from 20 Hz to 20 MHz) delivers higher accuracy measurements at low intensities.
