Application context

Why this design is used

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

Flow cytometry

OEM-AD-455: 454 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.

DNA sequencing

OEM-AD-455: 454 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.

Medical imaging

OEM-AD-455: 454 nm emission can be matched to the absorption or excitation band used in Medical imaging. The stated stability or noise figure (<2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.

Spectrum analysis

OEM-AD-455: 454 nm emission sets the excitation and detector-band choice for Spectrum analysis; linewidth and wavelength stability determine how cleanly weak spectral features can be separated from the laser line. The listed beam characteristic (~1.2) also controls focusing and collection geometry.

System integration

Integration and compatibility

Use these checks to connect OEM-AD-455 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Thermal management
Cooled method: Air cooled · Operating temperature (℃): 0-30
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
Beam divergence, full angle (mrad): ~1.2 · Beam diameter at the aperture (mm): 7.5*6
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.
