摘要： In a calibration reference light source and a sensitivity calibration system using the same, a plurality of single-wavelength light sources for emitting reference lights having mutually different single-wavelengths are used instead of a black body radiation source for radiating a white light, and not only the intensities of the single-wavelength reference lights, but also the wavelengths thereof are measured to obtain sensitivity correction coefficients of intensity-to-radiance conversion data. Thus, obtained reference radiance are highly reliable and sensitivity correction of spectrophotometers and spectral illuminometers can be performed with high accuracy and reliability at a user side, whereby the calibration reference light source and the calibration system using the same can be obtained at low cost.

摘要： A light receiving optical system includes: a relay optical system for converging light to be measured which has been converged on an image plane of an objective optical system on a view angle defining aperture for incidence through the view angle defining aperture. The light receiving optical system has the relay optical system with a relay lens operable to be selectively switched between a first and a second conjugated positions, and a first and a second light flux limiting aperture members disposed in proximity to the relay lens in the case where the relay lens is selectively switched between the first and the second conjugated positions. The relay optical system selectively forms, on the image plane of the objective optical system, an enlarged image and a reduced image of the view angle defining aperture in the case where the relay lens is selectively switched between the first and the second conjugated positions to define an incident light flux through the view angle defining aperture by a first and a second light flux limiting apertures, respectively, in the case where the relay lens is selectively switched between the first and the second conjugated positions. A spectrophotometer has the light receiving optical system.
