I have been building out a machine vision set-up for measuring dimensions and wanted to chat about optics. One of the primary advantages of a C Mount Telecentric Lens is eliminating perspective errors; therefore, an object's size will remain the same as the object moves away from or closer to the lens (within reasonable limits) - this is very important in metrology. C Mounts are a standard mounting interface used with industrial cameras, eliminating any complication of integrating them into your machine vision system; however, be aware that the lens diameter must be greater than the object’s size for proper function. Has anyone experienced any trouble with getting adequate lighting for using these lenses?
