Application context
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
MBL-F-457: 457 nm emission can be matched to the absorption or excitation band used in Fluorescence sensing. The stated stability or noise figure (<5%, <3%) helps keep measured intensity changes attributable to the sample rather than source drift.
MBL-F-457: 457 nm emission sets the excitation and detector-band choice for Raman spectroscopy; linewidth and wavelength stability determine how cleanly weak spectral features can be separated from the laser line. The listed beam characteristic (<1.5) also controls focusing and collection geometry.
MBL-F-457: 457 nm emission determines compatible optics, coatings and detectors for Laser printing. The catalogued beam parameter (<1.5) helps predict how the source will focus and propagate through the instrument.

Technical FAQ
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.
M2: <2.0 · Beam divergence (mrad): <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.
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.
