摘要： A fixed focus lens includes, numbered in order of location from an object side to an image side, a first lens, a second lens, a third lens, and a fourth lens. The first lens is a biconvex lens with a positive refractive power, and the second lens is a convex-concave lens with a negative refractive power. The third lens is a concave-convex lens with a positive refractive power, and the fourth lens is an aspherical lens having a negative refractive power in the centre portion thereof and a positive refractive power at the periphery portion thereof. The fixed focus lens satisfies the condition: 1.0>|(1/r2−1/r1)|>0.6, where r1 denotes the radius of curvature of a front surface of the second lens and r2 denotes the radius of curvature of a rear surface of the first lens.

摘要： An image projection system includes a light source device for providing unified light, a light modulator for receiving and modulating the unified light, and a projection device for receiving and projecting the modulated light onto a screen. The light source device includes a light-emitting unit capable of generating source light, and a light-uniform unit that has a light entrance side disposed to receive the source light, and a light exit side disposed to permit the unified light to exit the light-uniform unit. The light exit side includes an active area and an overfill area surrounding the active area. The light source device further includes a reflecting unit disposed to cover the overfill area such that the unified light at the overfill area that impinges the reflecting unit is reflected back toward the light-uniform unit and the light-emitting unit.
