Application context

Why this design is used

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

DNA sequencing

PGL-VI-940: 940 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.

Flow cytometry

PGL-VI-940: 940 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.

Medical imaging

PGL-VI-940: 940 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.

Measurement

PGL-VI-940: Measurement benefits from a stable, focusable source. 940 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (Near TEM00) informs waist size and propagation.

System integration

Integration and compatibility

Use these checks to connect PGL-VI-940 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Thermal management
Operating temperature: 0°C to 40°C
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 · Beam divergence, full angle (mrad): <1
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.
