The newest Compass 561 laser from Coherent delivers 50mW at 561nm, while still offering substantially lower noise than any other solid state yellow laser currently available.
Specifically, this frequency doubled, diode-pumped solid state laser has a noise specification of 0.25% RMS, from 10Hz to 1GHz, as well as excellent beam characteristics (M<1.2 and beam-pointing stability <6 urad/C).
In addition, Compass 561 utilises PermAlign construction to achieve superior reliability and lifetime characteristics, and is backed by a 13 month warranty, with unlimited operating hours.
These performance specifications, together with its compact size of 100x40x32.5mm, make this new Compass 561 an ideal laser for OEM bioinstrumentation applications, including flow cytometery, confocal microscopy and other types of bioimaging says Coherent.
In particular, the 561nm output is optimum for exciting several key fluorophores, such as rhodamine series and Alexa Fluor dyes, where it provides better separation between excitation and fluorescence than 532nm.
The Compass 561-50 laser has the same form, fit and function as the previous generation of both the Compass 561nm lasers and the Coherent Compass 532nm series, allowing OEM customers to take immediate advantage of the higher power at 561nm.
Coherent has shipped more than 40,000 Compass lasers with demonstrated lifetimes greater than 20,000 hours.
