NEW KAISER OPTICAL HOLOGRAPHIC NOTCH FILTER 690nm LASER
Kaiser Optical Laser Filter / Optics Mount Assembly
The Holographic Notch filter and the enhanced Holographic Notch filter, the SuperNotch filter, introduced in 1992 by Kaiser, are the standard filtering technology found in the majority of Raman spectrometers manufactured commercially and built by researchers currently. Our holographic filters can provide up to six order of magnitude of attenuation of the Rayleigh line along with sharp spectral cutoff s that allow bands as close as 100 cm-1 to be detected
