摘要： An optical lens assembly includes at least one optical element. At least one of the at least one optical element includes a multi-layer coating membrane, and the multi-layer coating membrane is formed by alternately stacking high refractive index layers and low refractive index layers. The multi-layer coating membrane is a dual-bandpass filtering membrane.

摘要： A light engine includes an image surface, a projected light surface, a projection lens assembly, and a plurality of folding elements. The image surface has three image areas. The projected light surface has three light sources that provide light with different wavelengths. The plurality of folding elements are arranged along a light emitting axis. The image surface and the projected light surface are substantially in parallel with the light emitting axis, and there is an air gap located between the image surface and the projected light surface. The three light sources respectively correspond to the plurality of folding elements and respectively correspond to the three image areas, and the light emitting axis and the projection lens assembly are disposed on the same optical path.

摘要： An optical waveguide plate has a front surface and a back surface, and includes an in-coupling element and an out-coupling element. The in-coupling element and the out-coupling element are disposed on at least one of the front surface and the back surface. An in-coupling area is an area of the at least one of the front surface and the back surface on which the in-coupling element is disposed, and an out-coupling area is an area of the at least one of the front surface and the back surface on which the out-coupling element is disposed. A thickness of the optical waveguide plate is gradually increased from the in-coupling area towards the out-coupling area.

摘要： An optical system includes an image surface, an aperture stop, a first and a second quarter-wave plate, a partial reflector, a reflective polarizer, a first and a second optical lens element. The image surface and the aperture stop are respectively at a front side and a rear side of the optical system. The first quarter-wave plate is between the image surface and the aperture stop. The partial reflector between the first quarter-wave plate and the aperture stop has an average light reflectivity of 35%. The second quarter-wave plate is between the partial reflector and the aperture stop. The reflective polarizer is between the second quarter-wave plate and the aperture stop. The first optical lens element between the image surface and the aperture stop has a convex front-side surface. The second optical lens element between the first optical lens element and the aperture stop has a concave rear-side surface.

摘要： An optical system includes an aperture stop, an image surface, a reflective polarizer, a partial reflector, first and second quarter-wave plates and first, second and third lens elements. The aperture stop and the image surface are respectively at a front side and a rear side of the optical system. The reflective polarizer is between the aperture stop and the image surface. The partial reflector is between the reflective polarizer and the image surface. The first quarter-wave plate is between the reflective polarizer and the partial reflector. The second quarter-wave plate is between the partial reflector and the image surface. The first lens element is between the aperture stop and the image surface. The second lens element is between the first lens element and the image surface. The third lens element has negative refractive power and is between the second lens element and the image surface.
