Application context
Typical uses for this laser type, with the selection logic tied to the model record.
MLL-W-473-SM: 473 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<2%) helps keep measured intensity changes attributable to the sample rather than source drift.
MLL-W-473-SM: 473 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<2%) helps keep measured intensity changes attributable to the sample rather than source drift.
MLL-W-473-SM: 473 nm emission can be matched to the absorption or excitation band used in Medical imaging. The stated stability or noise figure (<2%) helps keep measured intensity changes attributable to the sample rather than source drift.
MLL-W-473-SM: 473 nm emission sets the excitation and detector-band choice for Spectrum analysis; linewidth and wavelength stability determine how cleanly weak spectral features can be separated from the laser line. The listed beam characteristic (TEM00 (single mode fiber output)) also controls focusing and collection geometry.

Technical FAQ
Fiber connector: FC/APC · Fiber core diameter: 3.5um,0.10NA. Match the listed connector and fiber mode exactly; SMA905, FC/PC and FC/APC are not interchangeable, and a single-mode launch requires mode-field as well as numerical-aperture matching.
Cooled method: Water cooled · Operating temperature (°C): 10-30. Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
Transverse mode: TEM00 (single mode fiber output) · M2: <1.1. Size the downstream optics from the stated beam diameter and divergence rather than from the aperture of the housing, and confirm the polarisation state before specifying isolators or polarising optics.
Share wavelength, operating mode, output power or pulse energy, linewidth or pulse width, delivery, control, and safety requirements and we will qualify the matching configuration and lead time.
