Title:
IRRADIATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/002219
Kind Code:
A1
Abstract:
Disclosed is an irradiation device which has a reduced device size and is capable of irradiating irradiation light having a high degree of parallelisation, whilst limiting device costs. An artificial solar light irradiation device (1) is equipped with a lamp (10) for radiating light, an elliptical reflecting mirror (11) that is a concentrating reflecting mirror for concentrating the light from the lamp, a fly-eye lens (13) into which the luminous flux from the elliptical reflecting mirror (11) enters, and a collimation optical system (14) wherein the luminous flux which has passed through the fly-eye lens (13) is made to be parallel light, and irradiated on a sample placement surface (9) which is an irradiation surface. The artificial solar light irradiation device (1) is provided with a first mirror (20) for reflecting the luminous flux from the elliptical reflecting mirror (11) at an acute angle, and a second mirror (22) for reflecting the luminous flux reflected by the first mirror (20) at an acute angle; a spherical surface mirror (16) is provided in the collimation optical system (14); the fly-eye lens (13) is arranged in the optical path (L1) between the first mirror (20) and the second mirror (22); and the spherical surface mirror (16) is arranged such that the luminous flux reflected by the second mirror (22) is reflected toward the sample placement surface (9) in parallel to the optical axis (K1) of the elliptical reflector (11).
