WebThe resolving power of a telescope can be calculated by the following formula: resolving power = 11.25 seconds of arc/ d, where d is the diameter of the objective expressed in centimetres. Thus, a 25-cm-diameter objective has a theoretical resolution of 0.45 second of arc and a 250-cm (100-inch) telescope has one of 0.045 second of arc. WebJun 18, 2024 · The biggest advantage of using waveguide as an optical combiner is the optimization of space in the design of AR glasses.
