Title:
INTEGRATING SPHERE
Document Type and Number:
WIPO Patent Application WO/2014/162548
Kind Code:
A1
Abstract:
Provided is an integrating sphere in which light incident on a through-hole for a light receiving part for measuring a light quantity and a wavelength measuring part for measuring a wavelength is prevented from being emitted again from the through-hole without being incident on the light receiving part or the wavelength measuring part due to reflection or the like.
An integrating sphere (2) comprises an integrating sphere body (3) having a spherical space therein, a first through-hole (31c) for guiding light to be measured into the spherical space, and a second through-hole (33c) for guiding the light in the spherical space to a light receiving part (7), and in the second through-hole (33c), a wavelength measuring part (9) for measuring the wavelength of the light is provided in addition to the light receiving part (7).
