Application context

Why this design is used

Typical uses for this laser type, with the selection logic tied to the model record.

Flow cytometry

MRL-DP-640-A: 640 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<3%, <2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.

DNA sequencing

MRL-DP-640-A: 640 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<3%, <2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.

Medical imaging

MRL-DP-640-A: 640 nm emission can be matched to the absorption or excitation band used in Medical imaging. The stated stability or noise figure (<3%, <2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.

Collimation

MRL-DP-640-A: Collimation benefits from a stable, focusable source. 640 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (Near TEM00 (TEM00 optional)) informs waist size and propagation.

System integration

Integration and compatibility

Use these checks to connect MRL-DP-640-A 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: Near TEM00 (TEM00 optional) · Beam diameter at the aperture (1/e2, mm): <3.0
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.
