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.
