Steep cutoff (laser wavelength <0.2%) - high blocking performance - high transmittance.
The Nanoedge long pass filter is a high-performance hard coat filter that features a steep edge transition (less than 0.2% of the laser wavelength) at a specific wavelength, allowing it to transmit longer wavelengths while reflecting shorter wavelengths, thus enabling spectral separation. In particular, in Raman spectroscopy, it is necessary to separate Rayleigh scattered light (laser wavelength) from weak Raman scattered light, and the steep edge transition and high blocking performance make it easy to measure Raman spectra.
