Manufacturer of high volume precision optical and laser solutions Reo has released a 594nm (yellow) helium neon (HeNe) laser suitable for cost-sensitive bioinstrumentation and fluorescence excitation applications.  

The new laser features a circular beam profile and beam quality (M²<1.05) leading to minimised loss in a single mode fibre coupling. It also offers high polarisation purity (>500:1), with a guaranteed minimum output power of 2mW. Additionally, these yellow lasers provide low noise output (<1 per cent over the range 30Hz to 10MHz) and beam stability. Long term beam drift is under 0.05mrad.  They are packaged in an industry standard cylindrical head format (44.5mm diameter), and the front plate supports a variety of fibre coupling options. Reo offers a choice of OEM or CDRH-compliant power supplies, including time delay, key switch and interlock.
