Title:
SPECTRORADIOMETER
Document Type and Number:
WIPO Patent Application WO/2010/084957
Kind Code:
A1
Abstract:
A low-cost, compact, lightweight, high-speed, high-resolution, highly-efficient, and wide-band spectroradiometer for measuring the spectral characteristics of flashlight is implemented. Provided is a spectroradiometer characterized by being provided with an entrance slit (2) which light to be measured enters, an optical element (3) which converts the light to be measured that has passed through the entrance slit (2) into parallel light, a spectral element (4) which disperses the light to be measured emitted from the optical element (3), first and second light detecting means (8, 9) which detect spectral light dispersed by the spectral element (4), and a dichroic filter (5) which is provided in an optical system between the spectral element (4) and the first and second light detecting means (8, 9), wherein the first light detecting means (8) detects the spectral light in a first wavelength band, which has been transmitted through the dichroic filter (5), and the second light detecting means (9) detects the spectral light in a second wavelength band different from the first wavelength band, which has been reflected by the dichroic filter (5).
