Application context
Why this design is used
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
Carving
HPL-440-QM: 440 nm emission determines compatible optics, coatings and detectors for Carving. The catalogued beam parameter (<3.5) helps predict how the source will focus and propagate through the instrument.
Measure
HPL-440-QM: Measure benefits from a stable, focusable source. 440 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (<3.5) informs waist size and propagation.
Scientific research

System integration
Integration and compatibility
Use these checks to connect HPL-440-QM to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- Cooled method: Water 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): <3.5 · Beam diameter at the aperture (1/e2,mm): <6
- 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.
