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.
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.
