LOLS10在线直播下注As aspheres become more prevalent in optical systems, it is important for lens designers to consider the various tolerances when designing an aspheric lens. The following is provided from the manufacturers perspective on important tolerances to provide when designing an aspheric lens. Various topics discussed in this paper include irregularity and MSF errors (slope specification, maximum Zernike residual error, and spatial filtering), clear aperture, center thickness, and the dos and do nots of tolerancing aspheres.
