Nondestructive Examination of Optical Lens by Resonant Ultrasound Spectroscopy

공명초음파 분광법에 의한 광학기기용 렌즈의 비파괴 검사

As optical connectors dominate the performance of optical transmitters or receivers, they need an ultra-precise processing and are composed of optical fibers, ferrule and optical glass lenses. Therefore, this study suggests a nondestructive evaluation technique or a system using resonant ultrasound spectroscopy to evaluate flaws in a optical glass lens. It also conducted a nondestructive evaluation for flaws that are commonly found in a optical glass lens and reviewed the results.
