A light intensity variation measuring device capable of evaluating and inspecting the light distribution of a light source! The nine light-receiving sections can be installed at any position! It also supports low illumination and LED constant light!
The "DEF-9E" is a flash photometric tester that measures the light distribution of flash light. It enables the measurement and evaluation of brightness and illuminance uniformity for various lights. Additionally, it can accurately measure from a guide number of 0.078. The distribution of peripheral light intensity relative to the center is displayed in % and ΔEV. The nine light receiving points can be mounted at any position on a metal plate using magnets. The measurement range can be selected. *Up to 25 points can be measured. This measuring instrument is compatible with various applications. We can develop and propose solutions tailored to customer needs, such as illuminance uniformity measurement for LCD projectors. 【Features】 ○ Illuminance meter (illuminance uniformity tester) ○ Measurement accuracy: ±0.1EV ○ Low illuminance compatible ○ Measurable objects: - Xenon (Xe) flash - LED flash - LED constant light ○ Accurate measurement from a guide number of 0.1 ○ Displays the distribution of peripheral light intensity relative to the center in % and ΔEV ○ Light receiving points can be mounted in any location ○ Nine measurement points (up to 25 points possible) ○ Measurement range is selectable ● 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.
