WebSep 1, 2024 · In order to save space and achieve the system overall small size and light weight, the optical system output can be placed on a deviation from the sphere center. However, when the beam deviates from the center, it will cause the optical axis pointing error, which needs to be considered in the integrated design of the optoelectronic platforms. WebOn the horizontal (“X”) axis of the OPD diagram, there is the diameter of the lens, i.e. left side of the X axis can be considered as left side of the lens. On the vertical (“Y”) axis of the diagram we can see the actual Optical Path Difference. This is usually measured in “lambda”, i.e. the wavelength of light. simplebills service fee
