Application context
Typical uses for this laser type, with the selection logic tied to the model record.
UV-DP-349-B: 349 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<0.5%) helps keep measured intensity changes attributable to the sample rather than source drift.
UV-DP-349-B: 349 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<0.5%) helps keep measured intensity changes attributable to the sample rather than source drift.
UV-DP-349-B: 349 nm emission determines compatible optics, coatings and detectors for Optical instrument. The catalogued beam parameter (<1.2) helps predict how the source will focus and propagate through the instrument.

Technical FAQ
Cooled method (Water Cooled): WCH-580 · Operating temperature (℃): 10-35. Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
M²: <1.2 · Transverse mode: Near TEM00. 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.
