Series-level technical context
This model has no standalone PDF and only a small number of model-specific rows. The values below are traceable context from 11 nearby configurations on the same source-product record; they define the parameters to qualify, but are not substituted for an order-specific datasheet.
Nearby series records state M²: ~3.0, M²: <1.1, M²: <1.3, and Beam divergence, full angle (mrad): <3.0. These are series context, not guaranteed values for MSL-FN-3 55; confirm them on the order-specific datasheet.
Application context
Typical uses for this laser type, with the selection logic tied to the model record.
MSL-FN-3 55: 355 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.
MSL-FN-3 55: 355 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.
MSL-FN-3 55: 355 nm emission determines compatible optics, coatings and detectors for Optical instrument. Beam quality, divergence and pointing stability should be checked against the experiment geometry.

Choosing a laser
Which specifications decide the experiment, and which ones cost money without changing the result.
PhotonicsLinewidth, spectral width, RIN, M², and coherence length answer five different questions. Translate each into the units your experiment is designed in — and learn which ones not to pay for.
