Circular Variable Filter
10/12/2012
CI Systems’ Circular Variable Filters (CVF’s) are interference narrow-pass filters of advanced design which are deposited on circular substrates, called segments. Film thickness, and therefore the wavelength of peak transmittance varies linearly and continuously with angular position on the segment. CI Systems CVF’s are ideally suited as monochromators in compact, non-dispersive spectrometers, providing medium-resolution spectral radiation measurements, or when information is desired at a number of specific wavelengths in the relevant spectral range.
