A process lens is a specialized lens system designed for high-precision copying and reproduction of images, documents, or artwork. These lenses are engineered to provide exceptionally sharp focus, minimal distortion, and uniform illumination across the entire image plane.
Process lenses are commonly used in photography, printing, and graphic arts, where accurate reproduction of detail and colour fidelity is essential. Their superior optical quality ensures that every copied image retains clarity, contrast, and tonal accuracy, making them a critical tool in commercial and professional imaging workflows.
