Compact spectral irradiance probe has been designed and built which uses wedge filter in conjunction with silicon cell and operational amplifier. Probe is used to monitor spectral energy distribution of solar simulators and other high intensity sources.
Development and characteristics of spectroradiometer with wedge filters to eliminate adverse effect of pinholes in filters
Applying wideband autocollimator to Carco three axis test table for precision ultraviolet horizon sensor
Quantasyn provides absolute measurement of radiation flux in the range 1000 A to 4500 A and into the vacuum ultraviolet. This radiation detector cimbines the high quantum efficiency and inherent linearity of the silicon solar cell with the constant quantum response of the fluorescent organic compound liumogen.
