Application context
Why this design is used
Typical uses for this laser type, with the selection logic tied to the model record.
DNA sequencing
DL-HD-642: 642 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
DL-HD-642: 642 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
DL-HD-642: Collimation benefits from a stable, focusable source. 642 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.
