Ultraviolet optical filter Laserspec

infraredtunablelaser

Laserspec is the perfect laser plasma line filter for Raman spectroscopy. It is tunable, has excellent blocking characteristics and has an extremely broad wavelength range. Because Raman is a light scattering phenomena, unwanted radiation from laser plasma emission lines are often seen superimposed on the Raman spectrum making band assignment difficult and sometimes impossible. Fluorescence and other unwanted radiation can also be a considerable nuisance. Laserspec removes this unwanted radiation with little attenuation ensuring spectra free of unwanted line The optical design of Laserspec is prismatic and takes advantage of the very high transmission and dispersion characteristics associated with prismatic optics. As such Laserspec offers significantly higher transmission than diffraction grating monochromators or other filters and provides significantly better blocking characteristics. Prism materials are selected for each of two wavelength regions, i.e. ultra violet or visible to the near infrared.
