An optical microscope apparatus includes: a sample interrogation system configured to probe a sample location; and a light collection system configured to collect light output from a sample due to being probed by the sample interrogation system. The light collection system includes: a mirror positioned along an imaging axis that passes through the sample location; and an optical lens system including a plurality of optical lenses arranged along the imaging axis, at least one of the lenses being a multiplet optical lens.

According to examples, a system for image generation and delivery in a display device using two-dimensional (2D) field of view (FOV) expander is described. In addition, the system may include a first lens a first lens assembly having a first projector to propagate first display light associated with a first image and a first two-dimensional (2D) expander including a first waveguide for propagating the first display light to a first eye of a user and a second lens assembly having a second projector to propagate second display light associated with a second image and a second two-dimensional (2D) expander having a second waveguide for propagating the second display light to a first eye of a user.

A vibration device includes a light-transmissive body, and a vibrator to vibrate the light-transmissive body at a vibration acceleration of equal to or more than about 1.5×10.sup.5 m/s.sup.2 and equal to or less than about 8.0×10.sup.5 m/s.sup.2.

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, and a fifth lens. At least one lens among the first to the fifth lenses has positive refractive force. The fifth lens can have negative refractive force, wherein both surfaces thereof are 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 fifth lenses. The optical image capturing system can increase aperture value and improve the imaging quality for use in compact cameras.

The invention relates to an optical device (10) adapted to be worn by a wearer comprising at least: —a programmable lens (20) having an adjustable optical function and extending between at least one eye of the wearer and the real world scene when the optical device is worn by the wearer, —an optical function controller (30) comprising —a memory (32) storing at least computer executable instructions; and —a processor (34) for executing the stored computer executable instructions so as to control the optical function of the programmable lens (20), wherein the computer executable instructions comprise instructions for adjusting the optical function of the programmable lens (20) over a period of time determined so that the wearer does not perceive the adjustment of the optical function.

An optical imaging system is described including first to sixth lenses sequentially disposed from an object side to an image side, and an image sensor configured to convert incident light reflected from a subject, having passed through the first to sixth lenses, into an electrical signal. One of the first to sixth lenses includes a spherical object-side surface and another of the first to sixth lenses includes corresponding aspherical object-side surfaces. The first to sixth lenses include corresponding aspherical image-side surfaces, and a lens of the first to sixth lenses that is closer to the object side than the one of the first to sixth lenses including the spherical object-side surface, has a highest refractive index among the first to sixth lenses.

Aspects of the present invention relate to methods and systems for the see-through computer display systems with adjustable-zoom cameras positioned such that their respective capture fields-of-view at least partially overlap at a target distance.

An exit pupil expander (EPE) has entrance and exit pupils, a back surface adjacent to the entrance pupil, and an opposed front surface. In one embodiment the EPE is geometrically configured such that light defining a center wavelength that enters at the entrance pupil perpendicular to the back surface experiences angularly varying total internal reflection between the front and back surfaces such that the light exiting the optical channel perpendicular to the exit pupil is at a wavelength shifted from the center wavelength. In another embodiment a first distance at the entrance pupil between the front and back surfaces is different from a second distance at the exit pupil between the front and back surfaces. The EPE may be deployed in a head-wearable imaging device (e.g., virtual or augmented reality) where the entrance pupil in-couples light from a micro display and the exit pupil out-couples light from the EPE.

An annular optical component includes a plastic element and a metal element disposed on the plastic element. The plastic element includes a plastic part, and the metal element includes a metal part. The plastic part surrounds a central axis of the annular optical component so as to form a central opening. An outer annular surface and an inner annular surface of the annular optical component are opposite to each other. An object-side surface of the annular optical component faces an image-side direction of the annular optical component and is connected to the outer annular surface and the inner annular surface. An image-side surface of the annular optical component faces an image-side direction of the annular optical component and is connected to the outer annular surface and the inner annular surface. The image-side surface and the object-side surface are opposite to each other.
