摘要： Optical elements, color combiners using the optical elements, and image projectors using the color combiners are described. The optical elements can be configured as color combiners that receive different wavelength spectrums of light and produce a combined light output that includes the different wavelength spectrums of light. The optical elements include a wavelength selective dichroic mirror that reflects a major portion of actinic light that can damage a reflective polarizer within the optical element. The wavelength selective dichroic mirror transmits a major portion of other wavelengths of light. The resulting color combiners using the optical element may have improved durability compared to a color combiner lacking the wavelength selective dichroic mirror. Image projectors using the color combiners can include reflective (including digital micro-mirror) or polarization (including liquid crystal) imaging modules.

摘要： Optical elements, color combiners using the optical elements, and image projectors using the color combiners are described. The optical element includes light recycling stacks, a polarizing beam splitter, and a color-selective stacked retardation polarizing filter. The polarizing beam splitter includes a first reflective polarizer aligned to a first polarization direction. Each light recycling stack includes a second reflective polarizer aligned to the first polarization direction, and a retarder aligned at 45 degrees to the first polarization direction. The color combiner includes partially reflective light sources coupled to the optical element. Un-polarized light having different colors can enter the color combiner through the light recycling stacks, and combined light of a desired polarization state can exit the color combiner. Light having an undesired polarization state can be recycled to the desired polarization state within the color combiner, so that light utilization efficiency is increased. The image projector includes a color combiner coupled to an imaging source and projection elements, so that a first portion of the combined light is directed to the projection element, and a second portion of the combined light is recycled back into the color combiner.

摘要： Optical elements, color combiners using the optical elements, and image projectors using the color combiners are described. The optical element includes color selective dichroic filters and a reflective polarizer. A line passing perpendicularly through each of the color selective dichroic filters intercepts the reflective polarizer at approximately 45 degrees. The optical element can also include retarders positioned adjacent to the color selective dichroic filters. The color combiner includes partially reflective light sources coupled to the optical element. Unpolarized light having different colors can enter the color combiner through the dichroic filters, and combined light of a desired polarization state can exit the color combiner. Light having an undesired polarization state can be recycled to the desired polarization state within the color combiner, so that light utilization efficiency is increased. The image projector includes a color combiner coupled to an imaging source and projection elements, so that a first portion of the combined light is directed to the projection element, and a second portion of the combined light is recycled back into the color combiner.

摘要： Generally, the present invention relates to an apparatus for reducing astigmatism in a projection system that is particularly well suited to reducing astigmatism in LCD projection systems. A projection system includes a light source to generate light, conditioning optics to condition the light from the light source and an imaging core to impose on image on conditioned light from the conditioning optics to form image light. The imaging core includes a polarizing beamsplitter and at least one imager, and at least one element in the imaging core is adapted to reduce astigmatism in the image light. The astigmatism may arise in the polarizing beamsplitter. A projection lens system projects the astigmatism-reduced image light from the imaging core.

摘要： A compound polarization beam splitter (33) for use with a reflective, polarization-modulating, imaging device (10), e.g., a LCoS device, is provided. The compound PBS has: (a) an input prism (20); (b) an output prism (30), and (c) a polarizer (13), which is located between the two prisms (20,30) and which may be a wire grid polarizer (13a) or a multi-layer reflective polarizer (13b). Polarized illumination light (11) enters the input prism (20) through a first surface (21) and undergoes total internal reflection at a second surface (22) before being reflected from the polarizer (13) and polarization-modulated at the imaging device (10). The polarizer's tilt angle (β) is less than 45°, which reduces astigmatism and the required back working distance of the system's projection lens (74).

The PBS contains at least one prism having at least one major surface and having a refractive index of at least about 1.6 and a birefringent film disposed on the major surface of the prism. The birefringent film is a multi-layer film having layers of at least a first material and a second material. After uniaxial stretching, the film exhibits a refractive index difference of less than about 0.15 units in the stretched direction.
