“…In [3] there is described spectral irradiance scale based on custom made interference filters, which were used as the wavelengths selecting device for the detectors. Measurement of transmittance of the interference filters is considered to be easy but the requirements for uniformity, good long term stability, blocking outside filter's passband and residual infrared leakage are so strict that most of them are not suitable for this reason.…”

A method of luminous intensity measurement in accordance with new definition of candela adopted by the 16th International Committee of Weights and Measures in 1979 is described. Principal emphasis is placed in applying selfcalibrated photodiodes to the spectroradiometric measurements. The results of luminous intensity measurements with the CSMU photometric standard lamps are given. INTRODUCTIONThe relation between radiometric and photometric quantity is given by equationwhere)i and A2 are the limits of wavelength range in the visible. Spectral radiant intensity is a radiant quantity related to radiant flux by the equationwhere the spectral radiant flux. The solid angle over which light is collected is defined by the aperture area and the lamp/photometer distance. Luminous intensity in the relation (2) can be determined applying two main methods -broad-band photometry and spectroradiometric photometry. PRINCIPLE OF THE SPECTRORADI.QMETRLc REALIZATIONThe realization of the candela therefore involves dispersion of the radiation by a monochromator into spectral components. They are measured separately and the value of luminous intensity is determined numerically. There are several considerations behind the decision to use silicon photodiode detectors in the realization, rather than based on thermal device one.

“…1,2 Current NIR photodetector technologies rely on combining silicon or, to a lesser extent, III-V (InGaAs) with color filters or gratings. 3,4 This approach has proven to be functional and reliable, however, such wafer based photodetectors with extra filtering components fail to satisfy the new demands for wearable, cheap and flexible devices. In this direction, organic photodetectors (OPDs) are emerging as an appealing alternative, thanks to their flexibility, low embedded energy processing and high compatibility with available and easily scalable techniques such as roll to roll processing.…”
