An electronic device includes a carrier substrate having a front face. An electronic chip is mounted on the front face of the carrier substrate and includes an optical component. An encapsulation cover is mounted on top of the front face of the carrier substrate and bounds a chamber within which the chip is situated. A front opening extends through the cover and is situated in front of the optical component. An optical element, designed to allow light to pass, is mounted within the chamber at a position which covers the front opening of the encapsulation cover. The optical element includes a central region designed to deviate the light and having an optical axis aligned with the front opening and the optical component. A positioning pattern is provided on the optical element to assist with mounting the optical element to the cover and mounting the cover to the carrier substrate.

An apparatus for altering quantum of light passing through a lens of a photographic device. The apparatus comprises of a base assembly configured to be detachably coupled to the lens of the photographic device, a first assembly comprising a first filter, a second assembly comprising a second filter and a third assembly comprising a third filter. The first assembly is configured to be detachably coupled to the base assembly. The second assembly is configured to be detachably coupled to the base assembly. The third assembly is configured to be detachably coupled to the base assembly. Combination of the first filter and the second filter forms a first range of neutral density filter and combination of the first filter and the third filter forms a second range of neutral density filter.

Manufacturing an optical device includes providing a substrate (102) having a polymeric layer (104) on a surface of the substrate, forming openings in the polymeric layer, and depositing a material in the openings to form meta-atoms (114, 214) of a first metastructure. Adjacent ones of the meta-atoms are separated from one another by polymeric material of the polymeric layer. Optical devices that include one or more metastructures in which meta-atoms are separated from one another by polymeric material are described, as are modules that incorporate the optical devices.

An optical filter device (1000) includes: a first mirror (101) transmitting portion of incident light; a second mirror (201) spaced apart from the first mirror (101), and transmitting portion of the incident light; actuators (300) driving the first mirror (101) to change a space between the first mirror (101) and the second mirror (201); and a detection electrode (400) detecting displacement of the first mirror (101). The detection electrode (400) includes: a movable comb electrode (410) including movable combs (414) and connected to the first mirror (101); and a stationary comb electrode (420) including stationary combs (424) facing the movable combs (414) in parallel with each other. The movable combs (414) are displaced in parallel with the stationary combs (424) when the movable comb electrode (410) is displaced together with the first mirror (101).

Systems and methods reduce temperature induced drift effects on a liquid lens used in a vision system. A feedback loop receives a temperature value from a temperature sensor, and based on the received temperature value, controls a power to the heating element based on a difference between the measured temperature of the liquid lens and a predetermined control temperature to maintain the temperature value within a predetermined control temperature range to reduce the effects of drift. A processor can also control a bias signal applied to the lens or a lens actuator to control temperature variations and the associated induced drift effects. An image sharpness can also be determined over a series of images, alone or in combination with controlling the temperature of the liquid lens, to adjust a focal distance of the lens.
