Abstract: A system to provide radiant energy of selectable spectral characteristic (e.g. a selectable color combination) uses an integrating cavity to combine energy of different wavelengths from different sources. The cavity has a diffusely reflective interior surface and an aperture for allowing emission of combined radiant energy. Sources of radiant energy of different wavelengths, typically different-color LEDs, supply radiant energy into the interior of the integrating cavity. In the examples, the points of entry of the energy into the cavity typically are located so that they are not directly visible through the aperture. The cavity effectively integrates the energy of different wavelengths, so that the combined radiant energy emitted through the aperture includes the radiant energy of the various wavelengths. The apparatus also includes a control circuit coupled to the sources for establishing output intensity of radiant energy of each of the sources. Control of the intensity of emission of the sources sets the amount of each wavelength of energy in the combined output and thus determines a spectral characteristic of the radiant energy output through the aperture.

Abstract: The present invention relates to a rotationally asymmetric chaotic optical multi-pass cavity useful in optical gas sensing spectroscopy, optical delay lines, and laser amplification systems, for example. The cavity may include a single closed mirror having a light reflective surface that is deformed in two orthogonal directions and more particularly, but not exclusively, in the shape of a quadrupole in both horizontal and vertical planes. The cavity includes a light entry port and a light exit port which may be the same or separate ports, as well as a gas inlet and a gas outlet. The optical path length, the beam divergence rate, and the spot pattern are controlled by selecting the cavity deformation coefficients and the input beam direction to achieve the desired beam path and beam quality.

Abstract: Provided are a light source evaluation device, a light source adjustment system, a light source evaluation system, and a light source evaluation method whereby it is possible to evaluate the characteristics of a solar simulator, which is a light source for measuring the characteristics of a solar cell, without creating a reference cell or pseudo cell tailored to the spectral sensitivity of a solar cell to be measured. Said evaluation is performed by calculating an evaluation value of the characteristics of the light emitted by a solar simulator in comparison to natural sunlight on the basis of the spectral irradiance of the light emitted by a solar simulator as measured by a spectroradiometer, the spectral irradiance of natural sunlight, and the pre-measured spectral sensitivity of the solar cell to be measured.

Abstract: A sample that is an object whose quantum efficiency is to be measured, and a standard object having a known reflectance characteristic are each attached to a sample window provided in a plane mirror. Based on respective spectrums measured by a spectrometer in respective cases where the sample is attached and the standard object is attached, the quantum efficiency of the sample is measured. The plane of an opening of an observation window is made substantially coincident with the exposed surface of the sample or standard object, so that direct incidence, on the observation window, of the fluorescence generated from the sample receiving an excitation light and the excitation light reflected from sample is prevented.
