Q: What challenges arise when increasing the diameter of optics, such as aspheric lenses?
A: The CNC polishing equipment must have a broad range of motion and the lens’s weight becomes an issue. Measuring large aspheres is challenging, especially if the sagittal height hinders a tactile profilometer’s stylus. Using a larger stylus may compromise accuracy.
