Abstract

PURPOSE: To change film thickness and remove effective ripples by letting one layer out of the first, second, final layer and intermediate layers form the substrate side be a non-integer adjusting layer, in dichroic films composed of alternate layers of high refractive index layers and low refractive index layers and of a constitution of more than 10 layers.
