Abstract

PURPOSE:To solve uneven illuminance in exposure lighting or scanning optical apparatus by lighting narrow band light or single wavelength light to the detection position after transmitting through the vapor-deposition films whise transmissivity ratio is approximately inversely proportional to the decreasing illuminance by incident angle.
