Bandpass Filters for Laser-Induced Fluorescence
Bandpass filters for laser-induced fluorescence (LIF) are designed to transmit selected fluorophore emission bands while reducing unwanted out-of-band light, spectral crosstalk, and background noise. By blocking the intense laser excitation source (Rayleigh scattering) and isolating the longer-wavelength emitted light across the Stokes shift, these filters enable the detection of weak fluorescence signals in chemical, biological, and physical analysis.
Applications:
- Fluorescence microscopy and flow cytometry for isolating specific cellular emission signals from targeted fluorophores
- Combustion diagnostics and fluid dynamics for capturing species-specific fluorescence (such as OH or CH radicals) in reacting flows
- Environmental monitoring and chemical analysis for detecting trace contaminants, oils, and organic compounds using LIF spectroscopy
