MXY4000-13 Continuous Optical Transfer Function Measuring Instrument

1、 Product Introduction:

To measure the transfer functionThe interference pattern generated by the continuously variable stripe gap can be used as a flexible light target. The generation of precise targets, sine or square waves, or jumps used in optical components are necessary for evaluating the modulation transfer function and phase transfer function of the componentsThe research on the imaging process and image quality evaluation of optical systems is an important part of optical information processing. Based on spectral analysis methods and linear systems, the optical transfer function can objectively and effectively analyze the information transfer performance of the entire optical system by characterizing the transfer performance of the optical system to targets at different spatial frequencies. Therefore, it is widely used in optical design and optical inspection to measure the transfer function of continuous spatial frequencies.
