-Instrument Introduction

In the process of optical information transmission, the transmission process and quality of information are the main means of studying optical systems. Based on spectral analysis methods and linear system optical transfer functions, by characterizing the transfer performance of optical systems to targets at different spatial frequencies, the information transfer performance of the entire optical system can be objectively and effectively analyzed. Therefore, it is widely used in optical design and optical inspection.
