Application context
Why this design is used
Typical uses for this laser type, with the selection logic tied to the model record.
Spectrum analysis
MLL-III-1250-SM: 1250 nm emission sets the excitation and detector-band choice for Spectrum analysis; linewidth and wavelength stability determine how cleanly weak spectral features can be separated from the laser line.
Measurement
MLL-III-1250-SM: Measurement benefits from a stable, focusable source. 1250 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.
Flow cytometry
MLL-III-1250-SM: 1250 nm emission can be matched to the absorption or excitation band used in Flow cytometry. Power stability and beam pointing should be confirmed because both affect quantitative image or fluorescence intensity.
