Application context
Why this design is used
Typical uses for this laser type, with the selection logic tied to the model record.
Laboratory measurement
AO-DP-640: Laboratory measurement benefits from a stable, focusable source. 640 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (<2.0) informs waist size and propagation.
System integration
Integration and compatibility
Use these checks to connect AO-DP-640 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- Operating temperature(℃): 10~35 · Cooled method: Water Cooled
- 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 Diameter at the aperture 1/e2 (mm): ~1.5 · Beam divergence, full angle (mrad): <2.0
- 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.
