[New] Uniformity Analyzer UA-20series Launch

Topcon Technohouse Corporation be launch UA-20 series to respond to high-resolution measurement needs and trends in November 2022, following the well-received UA-10 series of luminance/chromaticity uniformity analyzer. The uniformity analyzer UA-20 series, is colorimeter instrument, realized 24.5 megapixels of resolution and wide dynamic range measurement at a low price, and is a small and light style that can be used widely from inspection of product line to performance evaluation of development. The UA-20 series launched as a lineup of luminance and colorimetric models UA-20C and luminance measurement models UA-20Y.

It is used in a wide range of fields and industries, including next-generation display panels such as Micro LEDs, Mini LEDs, and OLEDs, VR/AR products, various optical subsidiary materials, optical measurement of automotive parts, and research on color, color, color, electrical and electronic engineering at universities.
