Optical axis deviation
WebMar 19, 2024 · All distance is measured from the optical centre or pole and the sign convention we use is as shown below As we move towards the left from the optical centre, the value will be denoted by negative. Similarly, as we move below from the optical centre, the value will also be denoted by the negative sign. WebFeb 27, 2024 · Surface flatness is a specification for accuracy that measures the deviation of a flat surface with a lens, prism, mirror, or other optical components. This is done using an optical flat, which is a precise surface for reference to compare the deviation of the manufactured component. Surface Finish
