Title:
LIGHT STABILITY TESTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2003/002982
Kind Code:
A1
Abstract:
A light stability testing device comprising a light source, an optical system for regulating light emitted from the light source, a sample table for mounting thereon a sample to be irradiated with light passing through the optical system, and an optical sensor attached to the sample table, for measuring the dose of light, wherein the optical sensor has a visible light measuring sensor (5) for measuring the dose of visible light, a ultraviolet measuring sensor (6) for measuring the dose of ultraviolet ray, and an intermediate wavelength light measuring sensor (7) for measuring the dose of an intermediate wavelength light between visible light and ultraviolet ray, whereby the light stability testing device can conduct an accurate light stability test even on a medicine having a large degree of deterioration in an intermediate wavelength area (400 nm−500 nm).
