摘要: A process for the determination and correction of laser induced damages of the optical and electronic components within the beam path of a monitor module of a 193 nm excimer lasers is provided herein. Especially state of the art detectors like CCD cameras degrade under UV radiation. With a special correction of the sensitivity of each camera pixel this problem can be solved.
