Application context
Why this design is used
Typical uses for this laser type, with the selection logic tied to the model record.
Laboratory measurement
TEM-F-940: Laboratory measurement benefits from a stable, focusable source. 940 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 TEM-F-940 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): 25±3
- 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: <1.1
- 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.
