An object of the present invention is to provide a lens device that is configured such that a first optical-system and a second optical-system are combined to be concentric and that is capable of individually adjusting the light-amount of each optical-system and individually performing focus adjustment on each optical-system. The lens device, which is configured such that the optical-systems are combined to be concentric, comprises a first stop that adjusts a light-amount of the first optical-system and a second stop that adjusts a light-amount of the second optical-system. Thereby, it is possible to adjust individually the light-amounts of the optical-systems. Further, the first optical-system is provided to be movable along the optical axis L together with the first stop, and the second optical-system is provided to be movable along the optical axis L together with the second stop. Thereby, it is possible to individually perform focus adjustment on the optical-systems.

An optical image capturing system includes, along the optical axis in order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. At least one lens among the first to the sixth lenses has positive refractive force. The seventh lens has negative refractive force, wherein both surfaces thereof can be aspheric, and at least one surface thereof has an inflection point. The lenses in the optical image capturing system which have refractive power include the first to the seventh lenses. The optical image capturing system can increase aperture value and improve the imaging quality for use in compact cameras.

The present application discloses an imaging camera, including: a lens holder; a first lens unit, a stop, a second lens unit arranged in the lens holder in a sequence from an object side to an image side. An outer diameter of the first lens unit is greater than an outer diameter of the second lens unit. The stop includes a first supporting area abutting against the first lens unit, a second supporting area abutting against the second lens unit, and a connecting area abutting against the lens holder and connecting the first supporting area to the second supporting area. The first lens unit presses the first supporting area and forces the second supporting area to abutting against the second lens unit.

A near-eye display device includes a display panel and a plurality of light modulation units. The display panel includes a plurality of display pixel units configured to emit display light. The light modulation units are disposed on a light emitting surface of the display panel, and each of the light modulation units is disposed corresponding to one of the display pixel units. Each of the light modulation units is configured to direct the display light emitted from the corresponding display pixel unit to an eye of a user, and a width of the display light directed to the eye of the user is smaller than the pupil size of the eye. The user may still receive clear images when the near-eye display is out of focus because the display light directed to the eye has the width smaller than the pupil size.

The present disclosure describes optoelectronic modules (e.g., hybrid lens array packages) that have multiple optical channels, each of which includes at least one beam shaping element (e.g., a lens) that is part of a laterally contiguous array. Each optical channel is associated with a respective light sensitive region of an image sensor. Some or all of the channels also can include at least one beam shaping element (e.g., a lens) that is not part of a laterally contiguous array. In some cases, the arrays can include alignment features to facilitate alignment of the arrays with one another.
