Holographic Optical Components including the Holographic Notch and SuperNotchTM Filter, Holographic Bandpass Filter and the Holographic Transmission Grating have been developed to meet the needs of Raman spectroscopy applications. Combined as an integrated assembly, these holographic components in conjunction with a laser diode, CCD array or discrete detector and suitable collection and imaging optics form the basis of a new type of compact, robust and cost effective Holographic Raman Sensor suitable for process monitoring and control applications.
