Lens MTF Test Equipment
Introduction
ITRC provides customized lens MTF measuring system used for phone lens and digital camera lens. Modulation transfer function (MTF) measurement is an objective way to judge lens image quality. Compared with the single MTF value at a specified spatial frequency, MTF curve with respect to frequencies is preferred for judging lens quality. Based on this requirement, ITRC has developed an MTF measuring equipment. Vertical optical axis design makes machine compact and increases its accessibility. On-axis and off-axis measurement can be performed simultaneously in a single measurement.
