Abstract

PURPOSE:To improve the efficiency of infrared ray efficiency and form an infrared ray detector of high sensitivity and good response speed characteristics by setting the thicknesses of the vapor deposition electrodes provided on the front and back of a pyroelectric element. CONSTITUTION:There are the relations shown in the formula among incidence, absorption, reflection and transmission energies (respectively Ilambda, alambda, rlambda, dlambda) at wavelength lambda for the detecting part and the absorption, reflection and transmission energies for vapor deposition film thicknesses are expressed like, e.g., the figure. At the time of forming the detecting part by evaporating nickel, nickel-chromium or other on both sides of a pyroelectric element 21 such as of PVF2 (polyvinylidene fluoride) thereby forming a front electrode (infrared ray incident side) 22 and back electrode 23, the film thickness of the front electrode 22 is set at the thickness at which (rlambda + dlambda) becomes minimum and that of the back electrode 23 at the thickness of the range from the fall point of rlambda up to the rise point of dlambda.
