Imaging Brightness Meter P230U - Imaging Brightness Tester - Screen Imaging Brightness Meter

Imaging Brightness Meter P230U - Imaging Brightness Tester - Screen Imaging Brightness Meter Product Description:

Imaging Brightness Meter P230U - Imaging Brightness Tester - Screen Imaging Brightness Meter is used as a benchmark for measuring performance and measurement values. Using Sony's new model Pregius@CMOS Compared to previous versions of the brightness meter, the new series of sensors has faster photometric measurement speed and may be more accurate and sensitive than before. The specifications parameters for dynamic range, quantum efficiency, full well capacity, sensitivity, and noise have all been improved. Compared to CCD sensors, Pregius sensors also have significantly reduced noise.

Working Principle:

Industries related to lighting, such as indoor/outdoor lighting, automotive, aviation electronics, and healthcare, are regulated by global standards and recommendations. For example, the automotive industry must comply with UN ECE (Europe), CMVSS (Canada), or FMVSS (USA) and follow SAE recommendations. These standards define the allowable range and gradient of luminous intensity and color at different test positions under different measurement geometries and working conditions. The traditional method uses a goniometer and point detector, which is called the goniometer method. This method is time-consuming and can burden production and QA testing environments. The imaging method uses a 2-D imaging colorimeter and a diffuse reflectance screen, placing the imaging meter adjacent to the test source and focusing on the image formed on the screen. The system uses perspective transformation algorithm to calibrate the tilt angle of the camera and uses NIST traceable calibration source to calibrate the luminous intensity of the screen imaging system. Compared with the corresponding angle measurement method, the accuracy of this 2D imaging system should be within 10%; The measurement time has been reduced by at least 90%.
