Abstract
A beam combiner includes a first lens and a second lens coated with specific optical films. The first color light beam enters the first lens via a first incidence surface with an incidence angle of Brewster's angle. The second color light beam enters the first lens via the second incidence surface with an incidence angle of zero degree. The third color light beam enters the second lens via the third incidence surface with an incidence angle of zero degree. The first, the second, and the third color light beams transmit in the same path after the splitting face to form the composite light beam and come out via an exit surface.
