Application context
Typical uses for this laser type, with the selection logic tied to the model record.
OEM-DH-450: 450 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<1%, <3%, <5%) helps keep measured intensity changes attributable to the sample rather than source drift.
OEM-DH-450: 450 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<1%, <3%, <5%) helps keep measured intensity changes attributable to the sample rather than source drift.
OEM-DH-450: 450 nm emission can be matched to the absorption or excitation band used in Medical imaging. The stated stability or noise figure (<1%, <3%, <5%) helps keep measured intensity changes attributable to the sample rather than source drift.
OEM-DH-450: 450 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.
