Wideband Spectral Spatial Filter

 

Spectroscopic studies are frequently contaminated by disturbances such as fluorescence spectral noise, which occurs in Raman spectroscopy, or scattering noise, which occurs in both Raman spectroscopy and remote sensing.

 

Rayleigh scattering noise is produced by smoke particles and aerosols in remote sensing.

To avoid spectral noise, a spectroscopic instrument utilizes a variety of spectroscopic filters; however, these spectroscopic filters can't filter out Rayleigh's scattering noise.

 

The Wideband Spectral Spatial Filter from Lartec can mitigate both spectral and spatial noise. In both the spectral and spatial domains, Lartec's spectral noise filters may act as low-pass, high-pass, band-pass, edge-pass, long-pass, short-pass, dichroic filters, and notch filters.



Such a filter saves cost on purchasing on multispectral filters while also acting as spatial-spectral filters.
