Application context
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
MDL-NS-395: 395 nm emission can be matched to the absorption or excitation band used in Fluorescence excitation. The stated stability or noise figure (<3%, <2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.
MDL-NS-395: 395 nm emission sets the excitation and detector-band choice for Time resolve spectrum; linewidth and wavelength stability determine how cleanly weak spectral features can be separated from the laser line. The listed beam characteristic (Near TEM00) also controls focusing and collection geometry.

Technical FAQ
Cooled method: Air cooled · 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.
Transverse mode: Near TEM00 · Beam divergence, full angle (mrad): <0.5. 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.
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.
