👉 Monochromate is a term used in the field of optical engineering, specifically in the design and fabrication of lenses. It refers to a type of lens that has one color of light entering it as its primary transmission path. Monochromates are useful in various applications such as high-resolution imaging systems for medical imaging, where the choice of color is critical for image quality. Monochromate lenses can be designed with a single color of light passing through them, which allows for maximum contrast and
