Manufacturing
Performing manufacturing
Light interacts directly with the finished or intermediate product to change its physical properties, as in the case of photolithography or materials processing.
Controlling manufacturing
Optics is used to provide information about a manufacturing process, as in the chemical industry's use of optical sensors for in-line process control, or to inspect a manufactured
