A first prism block and a second prism block are connected to the polarizing beam splitter through the first filter and the second filter, respectively. The second prism block is a rectangular prism with a third filter formed on a base surface thereof. A third prism block is connected to the rectangular prism through the third filter. An angle formed by an inclined side of the rectangular prism and the base surface of the third filter is no more than 30°.
