Overview
ST2020 is an array Colorimeter developed by 3nh using its own spectroscopic core technology. It adopts a built-in large-area silicon photodiode array (dual row 20 groups) sensor, with excellent Repeatability and Inter-instrument Agreement. The measurement data is continuously stable, accurate and reliable, and can be used for accurate analysis and transmission of laboratory Color. The instrument is equipped with three measurement diameters of φ 8mm/φ 10mm platform, φ 4mm/φ 5mm platform, and 1x3mm, which is suitable for sample surface measurement with regular flat or curved radians.

9. Support USB, Bluetooth ® 5.0 interface, compatible with multi-platform software and massive Data storage.
Principle
The ST2020 array Colorimeter uses planar grating spectroscopy technology. Its D/8 illumination structure diffuses the light emitted by the combined full-spectrum LED Illuminant to the sample surface and receives the reflected light in the direction of 8 °. After the received rays of light pass through the spectroscopic system, they are captured by the large-area silicon photodiode array sensor to obtain the Light spectrum data of the sample, and then calculate various colorimetry parameters.
