Application context

Why this design is used

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

DNA sequencing

MSL-FN-335: 335 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<8) helps keep measured intensity changes attributable to the sample rather than source drift.

Flow cytometry

MSL-FN-335: 335 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<8) helps keep measured intensity changes attributable to the sample rather than source drift.

Cell sorting

MSL-FN-335: 335 nm emission determines compatible optics, coatings and detectors for Cell sorting. The catalogued beam parameter (TEM00) helps predict how the source will focus and propagate through the instrument.

System integration

Integration and compatibility

Use these checks to connect MSL-FN-335 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
Transverse mode: TEM00 · M2: <1.5
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.
