25 measurement points arranged in an arch shape! Display the flash light distribution and the vertical light distribution characteristics graph in a single measurement!
The "DEF-9900" is a flash light distribution tester that measures the light distribution characteristics of strobe flash light using 25 light receiving points (measurement points) arranged in an arch shape. It enables the measurement and evaluation of all types of light quantities, including brightness and illuminance. With a single flash, it displays the light distribution characteristic graphs on a computer screen for both vertical and horizontal orientations. It consists of a computer and a control unit. It is also capable of measuring LED constant light. * The number of light receiving points can be specified up to a maximum of 73. Please consult us. * Automatic pan-tilt head (optional) 【Features】 ○ Compatible with Xenon flash, LED flash, and LED constant light ○ Measures the light distribution characteristics of strobe flash ○ 25 light receiving points arranged in an arch ○ Measurement points: 25 points measured * Up to 73 points possible ○ Measurement accuracy: ±0.1EV ○ Composed of a computer and control unit ○ Displays the light distribution characteristic graphs on a computer screen for both vertical and horizontal orientations with a single flash ● For more details, please contact us or refer to 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.
