Application context

Why this design is used

Applications named on this model’s datasheet, expanded with the model’s optical specifications.

Scientific experiments

MLL-F-671: 671 nm emission determines compatible optics, coatings and detectors for Scientific experiments. Beam quality, divergence and pointing stability should be checked against the experiment geometry.

Laser-induced fluorescence

MLL-F-671: 671 nm emission can be matched to the absorption or excitation band used in Laser-induced fluorescence. The stated stability or noise figure (<3%, <2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.

System integration

Integration and compatibility

Use these checks to connect MLL-F-671 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Thermal management
Operating temperature (°C): 10-35
Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
Beam parameters at the output
Beam diameter at the aperture (1/e2, mm): ~3.0 · Polarization ratio: >100:1, Horizontal (Vertical optional)
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.
