Optical cycle tester for dew condensation

Abstract

Abstract PURPOSE:To perform a test under a high-precise condition, by a method wherein an electronic cooling element for heating or cooling a sample through a heat- transferring bottom plate of a test bath is located under the bottom plate, another electronic cooling element is situated to the side of the bath, and an ultraviolet lamps are positioned on the ceiling surface of the test bath. CONSTITUTION:If, in case an electronic cooling element 4 under a bottom plate 2 is cooled, air humidified by an ultrasonic system is fed to a test bath 1, dew is formed on a surface of a sample 3. The electronic cooling element 4 is then switched to heating, the humidified air is shut off, and an ultraviolet fluorescent lamp 7 is lighted. A cooling and a heating of the sample 3 can be freely regulated at a range of -10-+60 deg.C, and the temperature of the test bath 1 can be adjusted to a range of +10-+60 deg.C by cooling and heating an electronic cooling element 6 at a side. Finally, under a condition under which dew is formed on the surface of the sample 3, dew formation and ultraviolet irradiation can also be performed simultaneously.
