Application context

Why this design is used

Applications named on this model’s datasheet, expanded with the model’s optical specifications.

Medical imaging

MDL-C-400: 400 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.

Flow cytometry

MDL-C-400: 400 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<2%, <1%, <0.5%) helps keep measured intensity changes attributable to the sample rather than source drift.

DNA sequencing

MDL-C-400: 400 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<2%, <1%, <0.5%) helps keep measured intensity changes attributable to the sample rather than source drift.

System integration

Integration and compatibility

Use these checks to connect MDL-C-400 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 (°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.
Beam parameters at the output
Transverse mode: Multimode · Beam divergence, full angle (mrad): ~2.5×0.2
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.
