Abstract: A test fixture for holding and testing portions of an optical device, such as a plurality of cameras of an eyewear device. The test fixture includes a relay lens such that the fixture can be positioned close to a test screen displaying a patterned test image and reducing the size and cost of parts. The test fixture includes one or more lasers configured to easily and quickly align the test fixture. The test fixture includes an actuator for selectively positioning the cameras behind the relay lens to check for image quality.

Abstract: An infrared imaging system is formed by passively aligning two or more lens wafers including a plurality of lenses. The lens wafers may be pre-fabricated lens wafers in which the plurality of lenses are aligned utilizing an alignment jig having a plurality of conduits for distributing bonding material. Alternatively, the lens wafers may be formed of a base material molded around the plurality of optical lenses. The lens wafers may have a variety of alignment features, alignment inserts and/or alignment elements.

Abstract: In an embodiment, a method of aligning elements in a manufacturing process includes placing a middle element onto a base element, the base element forming first alignment features, the middle element forming apertures therethrough corresponding to the first alignment features. The method also includes placing second alignment features of an upper element onto the first alignment features such that the first and second alignment features cooperate, through the apertures, to align the upper element with the base element. An infrared lens assembly includes a lens formed of an infrared transmitting material that is disposed within a carrier of a base material, the lens being molded within the carrier with at least one feature that secures the lens to the carrier.

Abstract: A fluidic system comprising a force-transfer fluidic system with at least one fluidic component comprising a TDG sensor comprising in some embodiments an oxygen sensor, a luminescent oxygen sensor, or an electrochemical oxygen sensor. The system may further comprise a pressure transducer, a chamber and a membrane forming at least a portion of the chamber wall, the membrane being in direct or indirect contact with fluid or gas above the fluid. The TDG sensor may comprise control logic and an output of the control logic may be used directly or indirectly to control at least one process parameter of the system, including pressure and flow rate, and the control logic also may be used to notify the need for purification or to alert that a certain purity has been achieved.

Abstract: A passively athermalized infrared imaging system includes an object side meniscus lens that forms at least one aspheric surface, and an image side meniscus lens that forms two aspheric surfaces. Each of the meniscus lenses are formed of a material selected from the group consisting of a chalcogenide glass, germanium, silicon, gallium arsenide, zinc selenide and glass. An optical power of the image side meniscus lens is at least 1.6 times an optical power of the object side meniscus lens such that an effective focus position of the imaging system is athermalized over a range of 0 to +40 degrees Celsius.

Abstract: Systems and methods image with selective narrow FOV and 360 degree FOV onto a single sensor array. The 360 degree FOV is imaged with null zone onto the sensor array and the narrow FOV is imaged onto the null zone. The narrow FOV is selectively within the 360 degree FOV and has increased magnification as compared to the 360 degree FOV.
