Application context
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
MDL-NS-633: 633 nm emission can be matched to the absorption or excitation band used in Medical imaging. The stated stability or noise figure (<2%, <1%, <0.5%) helps keep measured intensity changes attributable to the sample rather than source drift.

Technical FAQ
Cooled method: Conduction · 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.
M2: <1.5 / <1.2 · Beam divergence, full angle (mrad): <1.0. 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.
Share wavelength, operating mode, output power or pulse energy, linewidth or pulse width, delivery, control, and safety requirements and we will qualify the matching configuration and lead time.
