    Abstract: A fixed focus lens includes a first lens group with a negative refractive power, an aperture stop, and a second lens group with a positive refractive power arranged in order from a first side to a second side. The first lens group has at least two lenses including at least one aspheric lens. The second lens group includes at least five lenses, the at least five lenses comprising a first compound lens and a second compound lens. A difference between a maximum Abbe number and a minimum Abbe number for all lenses of the first compound lens is greater than 50, and a difference between a maximum Abbe number and a minimum Abbe number for all lenses of the second compound lens is greater than 45.

    Abstract: A projection lens for a projection device having a light valve is provided. The light valve provides an image light beam. The projection lens includes a first lens group, a second lens group and a reflecting lens group. The second lens group is disposed between the first lens group and the reflecting lens group. The first lens group has positive refractive power. The second lens group has positive refractive power and includes a plurality of lenses and an aperture stop located between the lenses. An angle of a field of view of the second lens group is less than 100 degrees. The reflecting lens has negative reflective power and has a curved reflecting surface to reflect the image light beam passed through the second lens group.

    Abstract: A light combining module includes a first light source, a second light source, a first dichroic mirror, and an alignment structure. The first light source is used to output a first light. The second light source is used to output a second light. The first dichroic mirror is disposed on a transmission path of the first light and the second light, wherein the first light is incident on the second light source via the first dichroic mirror. The alignment structure adjusts the position of the second light source.
