Application context

Why this design is used

Applications named on this model’s datasheet, expanded with the model’s optical specifications.

Spectroscopy

MIL-W-3390: 3390 nm emission sets the excitation and detector-band choice for Spectroscopy; linewidth and wavelength stability determine how cleanly weak spectral features can be separated from the laser line. The listed beam characteristic (<11) also controls focusing and collection geometry.

Remote sensing

MIL-W-3390: 3390 nm emission determines compatible optics, coatings and detectors for Remote sensing. The catalogued beam parameter (<11) helps predict how the source will focus and propagate through the instrument.

Medical

MIL-W-3390: 3390 nm emission determines compatible optics, coatings and detectors for Medical. The catalogued beam parameter (<11) helps predict how the source will focus and propagate through the instrument.

System integration

Integration and compatibility

Use these checks to connect MIL-W-3390 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Thermal management
Cooled method: Air Cooled · Operating temperature (℃): 15-35
Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
Beam parameters at the output
Beam divergence, full angle (mrad): <11
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.
