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.

Company information
Since its establishment in 1965, Kyoritsu Electric has built a track record in the development of original products with the theme of "the fusion of light and electronics." Since 1971, we have supplied camera measurement instruments (exposure testers, luminance meters, flash testers, shutter testers, service testers, LED light sources, collimators, etc.) developed in-house, holding a significant market share primarily among camera manufacturers. Our long-cultivated optical measurement technology has been utilized in adjustment light source devices for digital cameras and video cameras, image sensor mounting alignment measurement instruments, flash light measurement instruments, and more, contributing to quality improvement. We obtained ISO-9001 certification in 1994 and are committed to traceable manufacturing. Additionally, we take pride in having a wide-ranging presence with agents in the United States, China, Taiwan, and South Korea. Moving forward, we are determined to refine our technology as a manufacturer contributing to the optical industry.
