Narrow-pass filters

These instruments use photon detectors which are semiconductor devices that are responsive only to a narrow band of wavelengths. Many narrow-bond thermometers further restrict the wavelength bandwidth by means of a narrow pass filter. In this case the total power detected is(4> ... [Pg.476]

For normal fluorescence scanning, a high intensity xenon continuum source or a mercury vapor line source is used, and a cutoff or narrow-pass filter is placed between the plate and detector to block the exciting UV radiation and transmit the visible emitted fluorescence. For fluorescence measurement in the reversed beam mode, a monochromatic filter is placed between the source and plate and... [Pg.1642]
