Application context

Why this design is used

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

Collimation

PGL-F-520: Collimation benefits from a stable, focusable source. 520 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.

Laser medical treatment

PGL-F-520: 520 nm emission determines compatible optics, coatings and detectors for Laser medical treatment. Beam quality, divergence and pointing stability should be checked against the experiment geometry.

Flow cytometry

PGL-F-520: 520 nm emission can be matched to the absorption or excitation band used in Flow cytometry. Power stability and beam pointing should be confirmed because both affect quantitative image or fluorescence intensity.

DNA sequencing

PGL-F-520: 520 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.
