Abstract: An augmented reality device, including a combiner, a laser projector, and a filter, where the laser projector is configured to emit a laser beam, the filter is mounted on the outer surface of the combiner, and a blocking band of the filter blocks a band of the laser beam. The combiner is configured to emit a part of the laser beam from the inner surface of the combiner, to emit a part of the laser beam from the outer surface of the combiner. The filter is configured to block the part of the laser beam emitted from the outer surface of the combiner, and the combiner is further configured to emit, from the inner surface of the combiner, after a part of ambient light whose wavelength is outside the blocking band passes through the filter, a part of the ambient light that enters the combiner.

Abstract: An optical module includes one or more laminating lenses where object side surfaces and image side surfaces of the laminating lenses are curved surfaces. The optical module also includes at least one of a linear polarizer, a first quarter-phase retarder, a partially transmissive and partially reflective film, a second quarter-phase retarder, and a reflective polarizer that are laminated to the object side surfaces or the image side surfaces of the laminating lenses. The object side surfaces or the image side surfaces of the laminating lenses are not designed as planes to facilitate diaphragm lamination.

Abstract: An eye-movement tracking apparatus and an electronic device are provided. The eye-movement tracking apparatus includes a light source, a lens group, a hot mirror, and a compact camera module. The light source is configured to emit a light ray to an eyeball of a user. The light ray is reflected by the eyeball to form a first light ray and a second light ray that are emitted to the lens group. The first light ray is reflected by the hot mirror for N times to form a third light ray. The second light ray is reflected by the hot mirror for M times to form a fourth light ray. Both M and N are natural numbers, and M and N are different. The optical component allow the third light ray to enter the image sensor, and prevent the fourth light ray from entering the image sensor.

Abstract: A method for bonding a film to a lens and a device for bonding a film to a lens includes a first jig and a second jig that are controlled to move relative to each other, to gradually bond a middle position to an edge position on the lens to the film, so that bubbles between the film and the lens can be reduced, and a good film bonding effect can be achieved. In addition, the method can be performed without processing the film in advance, and obtaining the lens through injection molding after the film is formed, so that optical performance or mechanical performance of the bonded film can be ensured.
