Abstract

DC60 (12/11/57) The optical component (1) consists of a photosensitive thin film (20), where the optical thin film (20) contains aluminum oxide as the main component. There is an aluminum oxide layer which has a coefficient of of the optical thin film (x) determined by the optical film thickness (nd) and the central wavelength (lamda0) in the range of 0.010 and above, not more than 2.00, and at the same wavelength of the central wavelength band, the amount of The shift of reflection rate 1 at normal temperature (R1) and reflection rate 2 at heating (R2) does not exceed 0.50%.
