Yellow laser is compact and high power
Unique combination of power and size means that these Compass all-solid-state lasers are suited to OEM bioinstrumentation applications, including confocal microscopy and live cell imaging
Two new Compass lasers from Coherent deliver more power from their compact packages than any Compass system previously available Specifically, the Compass 561 is now offered with either 40mW or 25mW of output power (at 561nm) from a laser head measuring only 100x40x32.5mm

Roses are red, lasers are violet
Violet laser producing power from 4mW to 30mW at 408nm for series a range of applications including cytometry, high-throughput screening, and confocal microscopy
The yellow wavelength enables solid-state access to fluorophores, such as rhodamine series and Alexa Fluor dyes, which traditionally were excited only using krypton ion lasers.
Compass 561 lasers also offer superior performance in terms of output characteristics.
For example, they possess the lowest noise specification (<0.25%RMS at 10Hz to 1GHz) of any yellow laser, resulting in data with a superior signal-to-noise ratio.
High transverse mode quality (M<1.2), coupled with excellent beam-pointing stability (<6urad/C), make it possible to achieve and maintain excellent throughput with microscope optics.
Compass 561 lasers are also extremely rugged and reliable because they use the same PermAlign manufacturing technology that has proven itself in over 40,000 Compass units currently in the field.
Coherent Compass 561 operates at yellow (561nm) wavelength.
