Inverse projection type MTF measurement device

Inverse projection type MTF measurement device

Lens resolution performance evaluation device! Minimal error impact from the camera! Can also be used for acceptance testing!

MTF refers to the ability to reproduce the subject with a certain degree of fidelity, represented by contrast with spatial frequency on the horizontal and vertical axes. Through MTF measurement technology, we provide complete inspection in lens manufacturing, development considerations, and optical axis adjustment devices for lenses and cameras. A reticle placed at the focal plane of the lens under test is illuminated with collimated light and imaged by a camera using a reverse projection method. Since the enlarged image is processed, the influence of errors from the camera is minimized. We can propose MTF measurement, various image evaluation charts, light sources, and software according to your needs. Please feel free to consult us. 【Features】 ○ High-speed parallel processing - Camera image acquisition and MTF calculation are processed in parallel. This brings the MTF calculation time close to zero, achieving speedup. ○ High precision and high stability - Excellent measurement stability achieved through our unique super-sampling technology based on ISO12233. ○ Minimal error influence from the camera due to processing of enlarged images. ○ Halogen lamp fiber light source spectral correction. * Near-infrared light source (optional). ○ Measurement of infrared camera lenses for industrial cameras is also possible. ● For more details, please contact us or download the catalog.
