561 NM LASER (DPSS; FREE-SPACE)
描述
The compact 561 nm module is a DPSS laser featuring high output power, very good beam quality and superior long-term power stability. The lower-coherence version features several longitudinal modes at higher power and typically single-longitudinal mode at a power level of ~10 mW. 561 nm wavelength radiation is commonly used in fluorescence excitation, scanning microscopy and general yellow light illumination. The free-space version features small beam diameter, very small form factor and wide operational temperature range from 15 deg. to 45 deg. C.
