Abstract

Lens processing and testing systems are provided various forms of marking and/or holding lens components, such as lens substrates and the like including electro-active elements. A lens testing system may include, for example, a light source, a first polarizer, a second polarizer, and a camera. The device may be configured to hold a test lens between the first and second polarizers and to shine light from the light source through the first polarizer, through the test lens, and through the second polarizer, and to receive the light in the camera. Exemplary systems may also include various holding and/or marking features to properly align the lens component to be tested or processed. For example, a lens including an electro-active element may be marked according to a predetermined offset from the center of the electro-active element and may be aligned based on the offset marks.
