About This Product

■Summary

There are two types of edge filters, long-pass and short-pass.They have excellent edge steepness at a certain wavelength, and can perform spectral separation by transmitting and reflecting the wavelength ranges before and after. Longpass filters transmit wavelengths longer than a specific wavelength and reflect wavelengths shorter than a specific wavelength, while shortpass filters transmit wavelengths shorter than a specific wavelength and reflect wavelengths longer than a specific wavelength. Particularly in Raman spectroscopy, it is necessary to separate Rayleigh scattered light (laser wavelength) and weak Raman scattered light, but the excellent edge steepness and high blocking performance make it easy to measure Raman spectra.

■About Iridian filters

Conventional filters are produced by bonding multiple glass substrates and coatings together using electron beam evaporation. Iridian's filters are formed and manufactured by sputtering deposition on a single glass substrate. This has significantly improved durability, which was a problem with conventional filters, and the deterioration of optical properties due to the passage of time and the surrounding environment. It also has many excellent features such as high transmittance, high blocking performance, and excellent edge steepness.

■Features

・Excellent edge steepness: Can be detected closer to Rayleigh light (excitation laser wavelength) than with a notch filter ・High blocking performance (OD > 6) ・High transmittance (average transmittance 90%): Detects even weak Raman scattered light ・High laser resistance: Can be used for a long time

■Applications

・Raman spectroscopy ・Laser excitation ・Fluorescence measurement ・Biophotonics ·microscope
