Series-level technical context
Engineering context for a thin CW Lasers record
This model has no standalone PDF and only a small number of model-specific rows. The values below are traceable context from 2 nearby configurations on the same source-product record; they define the parameters to qualify, but are not substituted for an order-specific datasheet.
Typical operating fields in the series
- • Output / average power: 1~20 mW
- • Output / average power: 1~50 mW
- • Operating mode: CW
- • Power stability (rms, 4 hours ± 3°C): <2%, <1%, <0.5%
Beam-quality tolerance context
Nearby series records state M²: <1.1, M²: <1.5, Beam divergence, full angle (mrad): <1.5, and Beam divergence, full angle (mrad): <1.0. These are series context, not guaranteed values for MLL-III-685-SM; confirm them on the order-specific datasheet.
Optical integration schematic
- Step 1Laser head and temperature-stabilized base
- Step 2Safety shutter and optional optical isolator
- Step 3Beam steering, expansion or fiber-launch optics
- Step 4Experiment input with wavelength-matched coatings

Why this design is used
Typical uses for this laser type, with the selection logic tied to the model record.
DNA sequencing
MLL-III-685-SM: 685 nm emission can be matched to the absorption or excitation band used in DNA sequencing. Power stability and beam pointing should be confirmed because both affect quantitative image or fluorescence intensity.
Medical imaging
MLL-III-685-SM: 685 nm emission can be matched to the absorption or excitation band used in Medical imaging. Power stability and beam pointing should be confirmed because both affect quantitative image or fluorescence intensity.
Collimation
MLL-III-685-SM: Collimation benefits from a stable, focusable source. 685 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.
