Handheld Luminance Meter "BM-9A"
Lightweight and compact with optical separation, significantly improved brightness accuracy and measurement range!
The "BM-9A" is a lightweight, compact, and portable handheld luminance meter. As a successor to the long-popular "BM-9," it maintains a similar price while significantly improving luminance accuracy and measurement range. By selecting and exchanging three types of light sensors with different measurement angles, it can be used for a wide range of applications. Additionally, the light sensor can be separated from the main unit, making it suitable for use in system devices and production lines. 【Features】 ■ Handheld, low-cost, multifunctional ■ Three types of light sensors can be selected and exchanged, automatically recognized, and measurement results displayed directly ■ Built-in USB for communication with PCs and use in production lines and system devices ■ Keyboard unit allows selection of correction factors and deviation measurements For more details, please contact us or download the catalog.

Fine Tech Japan Specialized Technology Seminar "Chromaticity and Uniformity Inspection in Micro LED"
At the 28th Fine Tech Japan (LCD, Organic EL, Sensor Technology Exhibition) specialized technical seminar, I will also be giving a presentation. As μLED is becoming the mainstream device to meet the expanding display's color gamut and contrast, the uniformity of brightness and chromaticity has become an issue due to the intensification of self-emission. The world's first developed two-dimensional spectral radiance meter, SR-5000, can analyze subpixels smaller than 2um! In this presentation, I will introduce examples. ■ "Chromaticity and Uniformity Inspection in Micro LED" Presentation December 7 (Friday) 9:30–10:20 Optical Measurement Department Sales Group Manager Kazuto Nishikawa We sincerely look forward to your attendance!

Sales started in March 2014: Topcon Technohouse's successor to the handheld luminance meter 'BM-9A'
Topcon Technohouse Co., Ltd. has developed the "BM-9A," a successor to the handheld luminance meter "BM-9," significantly improving luminance accuracy and measurement range. Sales will begin in March 2014. The luminance measurement range has been expanded from the previous model's 0.01 to 19,990,000 cd/m² to 0.01 to 28,000,000 cd/m², and the luminance accuracy guarantee has been improved from ±4% to ±2%. As with the previous model, three types of measurement angle light receiving heads (2°, 1°, 0.2°) can be selected and exchanged. It also comes standard with USB communication and analog signal output functions, and a new zero correction function without a cap has been added, making it even more suitable for embedded applications as a "luminance sensor" in customer production processes and various industrial devices. By connecting an oscilloscope or similar device to the analog signal output, it is possible to measure response and flicker light. Additionally, it can be powered by AA batteries, allowing for the measurement of reflected luminance on floors and the luminance evaluation of guiding blocks for visually impaired individuals outdoors. Furthermore, measurement data collection via PC using the standard application software MT-100 is also possible.
