Abstract: Spectrophotometer for the characterisation of receivers of solar collectors in order to determine optical properties (transmittance and reflectance). The equipment allows the evaluation of a receiver tube in real time and in any kind of light conditions, both inside and outside. The equipment also allows the detection of the eccentricity between the outer tube and the inner tube, which directly influences the reliability of the measurement. The equipment has a mechanical system for allowing a rotation of the equipment around the tube in order to find the optimum measurement position and attach itself to the tube.

Abstract: Photoluminescence quantum yield (PLQY) testing of quantum dots is described. In one embodiment, a method involves heating a sample including quantum dots and illuminating the sample with a light source. The method involves measuring spectra of luminescence from the illuminated quantum dots of the sample at each of a plurality of temperatures. The method involves measuring each of the plurality of temperatures with a temperature sensor. The PLQY at each of the plurality of temperatures is computed based on the measured spectra. The method further involves computing a relationship between QD emission wavelength of the measured spectra and the plurality of temperatures measured with the temperature sensor. The relationship is used to determine the QD temperature corresponding to each of the PLQY computations. In one embodiment, an integrating sphere moves on a gantry over the samples.

Abstract: A method of determining lighting contributions of elements of a lighting component includes obtaining optical data representative of light output of the lighting component. Relative intensity data may be calculated from the optical data, and may indicate intensity differences in the light output of the lighting component as compared to that of a reference component. An optical property of an element of the lighting component is determined based on a comparison of the optical data with that of the reference component, where the reference component includes at least one reference element. Related systems and apparatus are also discussed.
