Applications

  • Laser Applications — Enables laser cleanup, line filtering, and excitation filtering by isolating a laser’s fundamental emission line and precise excitation wavelengths while suppressing unwanted spectral components.
  • Medical & Life Sciences — Supports PCR diagnostics, DNA sequencing, and fluorescence microscopy by providing the wavelength selectivity needed for accurate signal detection and clean separation of fluorescent labels.
  • LiDAR — Delivers stable, narrow-band transmission at the system’s operating wavelength, maintaining performance under temperature cycling in field conditions.
  • Raman Spectroscopy — Enables clean rejection of Rayleigh-scattered light while preserving weak Raman signals near the laser line.
  • Flow Cytometry — Isolates specific fluorophore emission wavelengths in flow cytometry, reducing spectral cross-talk between channels and enabling accurate discrimination of closely spaced fluorescent signals during multiparameter analysis.
