Optical sensing

MIL-U-1085-SU: 1085 nm emission determines compatible optics, coatings and detectors for Optical sensing. The catalogued beam parameter (TEM00) helps predict how the source will focus and propagate through the instrument.

Measurement

MIL-U-1085-SU: Measurement benefits from a stable, focusable source. 1085 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (TEM00) informs waist size and propagation.

System integration

Integration and compatibility

Use these checks to connect MIL-U-1085-SU to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Thermal management
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.
Beam parameters at the output
Transverse mode: TEM00 · M2: <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.
