Compatible with large-diameter interchangeable lenses, equipped with AV value measurement function! A high-precision top-of-the-line aperture area meter! Hysteresis evaluation possible with high sampling!
The "AFD-2000" is a high-precision top-tier AV tester that supports large diameters. It can measure the aperture diameter area of interchangeable lenses (AV value measurement). Continuous operation from wide open to minimum aperture (1000 times/second) for aperture diameter evaluation is possible. Hysteresis evaluation is achievable through high sampling. It is suitable for the development, evaluation, and inspection of autofocus functions during video recording. The measurement accuracy is ±0.02EV, and the external interface is USB. 【Features】 ○ AV Tester ○ Measurement of the aperture diameter area of interchangeable lenses ○ Effective measurement diameter: φ1.0–45 ○ Measurement display ・[EV]: -13.10 to +13.10 ・[AV]: 0.00 to +15.10 ○ Continuous operation (1000 times/second) for aperture diameter evaluation from wide open to minimum aperture ○ Hysteresis evaluation through high sampling ● 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.
