Application context
Why this design is used
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
Optical sensing
MLL-U-946-SU: 946 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
MLL-U-946-SU: Measurement benefits from a stable, focusable source. 946 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (TEM00) informs waist size and propagation.
Instrumentation
MLL-U-946-SU: 946 nm emission determines compatible optics, coatings and detectors for Instrumentation. The catalogued beam parameter (TEM00) helps predict how the source will focus and propagate through the instrument.
System integration
Integration and compatibility
Use these checks to connect MLL-U-946-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.
