<P>PROBLEM TO BE SOLVED: To provide an environmental test apparatus with a pseudo solar light irradiation device, which can be used for the light durability evaluation of various materials, electronic apparatuses and electronic components under predetermined temperature/humidity or cell characteristic evaluation of solar cells under the predetermined temperature/humidity and achieves miniaturization, high performance and reduction in maintenance cost. <P>SOLUTION: The environmental test apparatus includes: a test chamber in which an object to be tested is stored; air conditioning means for adjusting air in the test chamber at predetermined temperature/humidity; a lighting window composed of a window formed on a part of the outer wall of the test chamber in order to guide pseudo solar light into the test chamber and provided with dew condensation prevention means composed of a transparent material of which the light transmittance at 350 nm wavelength is 70% and more; and pseudo solar light irradiation means arranged on the outside of the test chamber to applying pseudo solar light into the test chamber through the lighting window. The pseudo solar light irradiation device includes an irradiation lens unit composed of a single rod lens and a collimator lens arranged on the back of the rod lens. <P>COPYRIGHT: (C)2012,JPO&INPIT |
