Abstract
A color separation optical system includes a set of prisms which separate incident light into components having different wavelengths. Image pickup devices may be exposed to the separated light components. An arrangement prevents or reduces the influence of a temperature variation upon color separation characteristics. The color separation optical system maybe manufactured in a new way.
