Customize Raman Optical Filter China Manufacturer
In Raman spectroscopy equipment, filters selectively filter out unnecessary light. Filters can separate excitation light from Raman signals to avoid interference of laser light sources on Raman signals. This improves the quality and accuracy of Raman signals.
Coligh is specialized in Raman filters manufacturing. The filters include bandpass exitation filter, longpass emission filter and edge dichroic filter also some notch filters.
Our filters have advantages over:
- Efficiently block lasers and avoid interference of lasers on detection systems
- Ultra-narrow bandpass filters can select and transmit the required Raman signals and shield light of other wavelengths
- Deep cutoff blocks lasers and other stray light, and high transmittance enhances weak Raman signals to form an ultra-high signal-to-noise ratio
- Ultra-narrow bandpass filters can accurately select the wavelength range of interest and improve the resolution of Raman spectra
