Featuring a high output power semiconductor laser diode with thermoelectric cooler and integrated drive and protection electronics in a single, compact easy to use package
Pro-Lite Technology, a specialist photonics distributor, announces the product release of two new laser diode modules from Blue Sky Research.
The Chromalase 635 features a high output power 635nm semiconductor laser diode with thermoelectric cooler and integrated drive and protection electronics in a single, compact easy to use package measuring 158x38mm.
The housing is designed to fit standard circular or square laser mounts as a drop-in replacement for HeNe lasers.
This module does not require any external or fan assisted cooling maintaining low noise, excellent power stability and pointing stability.
The laser diode utilises BSR's patented and proprietary ulens technology which converts the laser diode output into a diffraction limited circular beam.
BSR laser diodes utilising this ulens are also known as Circulaser or VPSL (virtual point source) lasers.
The microscopic lens is located inside the laser header package itself so no additional external anamorphic optics or optics to shape the beam and remove astigmatism are required.
Collimation is achieved with a simple collimating lens offering a choice of exit beam diameters.
Output powers of up to 25mW at 635nm are now available at lower prices than the HeNes they are replacing in applications such as flow cytometery, biomedical research, particle sizing, inspection and metrology.
Power adjustment is possible by a manual knob on the laser body.
Input required is 5V/3.3V DC and power consumption is <4 W.
The Chromalase 405 features the latest gallium nitride laser diodes, circularised and corrected utilising BSR's proprietary ulens technology. Similar to the 635nm module this laser provides up to 25mW at the violet wavelength of 405nm and is particularly suited to computer graphics printing, CD mastering, medical instrumentation and confocal microscopy as examples.
Input power required is 7V DC and total power budget is <10W thereby requiring no forced cooling.
Other wavelengths shortly to become available include 375nm, 440nm and in the same package a laser at 532nm.
