ABSTRACT:
A dielectric multilayer film which has a bandpass characteristic in which a light beam having a wavelength .lambda.2 passes and a light beam having any of the other wavelengths is blocked is formed on the emergent-side surface of a lens provided near a light-receiving device which receives a light beam having the wavelength .lambda.2. A dielectric multilayer film which has a bandpass characteristic in which a light beam having a wavelength .lambda.1 passes and a light beam having any of the other wavelengths is blocked is formed on the emergent-side surface of a lens provided near another light-receiving device which receives a light beam having the wavelength .lambda.1.
