Source Based StandardsDetector Based StandardsSpectral Irradiance StandardsLuminance StandardsSpectral Radiance StandardsSpectral Responsivity StandardsReflectance StandardsGeometry Adjusted Calibration StandardsEvery optical radiation detection or measurement system needs to be calibrated in reference to an optical radiation source. There are two possible ways to perform the calibration: 1. The source can be calibrated in the required quantity and the difference between the input signal generated by the source and the output signal of the detection See more on gigahertz-optik Newport
