Title:
STANDARD SPECTRORADIOMETER
Document Type and Number:
WIPO Patent Application WO/2010/084956
Kind Code:
A1
Abstract:
Provided is a standard spectroradiometer which accurately measures the spectral radiation characteristics of a solar simulator and has the function of diagnosing a light source lamp and a lighting circuit thereof. In the standard spectroradiometer provided with first light detecting means (91-95), flashlight emitted from a pulse lighting solar simulator (2) is split and conducted through a plurality of optical fibers (71-75), the conducted flashlight is dispersed by respective spectroscopes (81-85), and spectral light obtained by the dispersion is detected by respective first light detecting means (91-95). The standard spectroradiometer is characterized by being provided with a second light detecting means (10) for detecting the flashlight emitted from the solar simulator (2), a threshold determining circuit (13) for comparing detected voltage detected by the second light detecting means (10) and threshold reference voltage and outputting a determination signal when the detected voltage is higher than or equal to the threshold reference voltage, and a delay time generating circuit (14) for receiving the determination signal and outputting a measurement start signal, wherein each of the first light detecting means (91-95) starts the detection upon receiving the measurement start signal.
