Application context
Why this design is used
Typical uses for this laser type, with the selection logic tied to the model record.
Laboratory measurement
EO-XS-671: Laboratory measurement benefits from a stable, focusable source. 671 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (<3) informs waist size and propagation.
System integration
Integration and compatibility
Use these checks to connect EO-XS-671 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 (℃): 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
- Beam divergence, full angle (mrad): <3 · Beam diameter at the aperture (1/e2,mm): ~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.
