Application context

Why this design is used

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

DNA sequencing

MLL-III-785-Lock: 785 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.

Flow cytometry

MLL-III-785-Lock: 785 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.

Medical imaging

MLL-III-785-Lock: 785 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.

Measurement

MLL-III-785-Lock: Measurement benefits from a stable, focusable source. 785 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (Multimode) informs waist size and propagation.

System integration

Integration and compatibility

Use these checks to connect MLL-III-785-Lock to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Thermal management
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.
Beam parameters at the output
Transverse mode: Multimode · Beam divergence, full angle (mrad): <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.
