Abstract:
A light-mixing module includes a first plate, a second plate, a first dichroic mirror, a second dichroic mirror, and a third dichroic mirror. The first dichroic mirror is disposed between the first plate and the second plate and is substantially perpendicular to the first plate and the second plate. The second dichroic mirror is disposed on a first side of the first dichroic mirror. The second dichroic mirror forms an angle with the first dichroic mirror and is substantially perpendicular to the first plate and the second plate. The third dichroic mirror is disposed on a second side of the first dichroic mirror and is substantially perpendicular to the first plate and the second plate. The third dichroic mirror is substantially parallel with the second dichroic mirror. The second dichroic mirror and the third dichroic mirror together form a fourth dichroic mirror, and at least one of the first dichroic mirror and the fourth dichroic mirror has a bevel gradient dichroic film.
