Application context

Why this design is used

Typical uses for this laser type, with the selection logic tied to the model record.

Optical instrumentation

MGL-FN-543.5: 543.5 nm emission determines compatible optics, coatings and detectors for Optical instrumentation. The catalogued beam parameter (TEM00) helps predict how the source will focus and propagate through the instrument.

Laboratory measurement

MGL-FN-543.5: Laboratory measurement benefits from a stable, focusable source. 543.5 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 MGL-FN-543.5 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 · Polarization Ratio: >100:1, Vertical (Horizontal Optional)
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.
