Spectral Characterization Of Cooled Filters For Remote Sensing
Abstract
The improvements obtained on cooling atmospheric remote-sensing instruments for space flight applications has promoted research in the characterization of optical filters necessary for spectral selection. By modelling the effects of temperature on the dispersive spectrum of some constituent thin film materials, the cooled performance can be simulated and compared. Two actual filters are discussed for the 7 pm region, one a composite cut-on/cut-off design of 13% HBW and the other an integral narrowband design of 4% HBW.
