Overview
DS-100 spectroscopic color difference meter is a portable spectroscopic color difference meter under the DOHO brand, using independent spectroscopic core technology. The instrument not only ensures the accuracy of the relative value of color difference Delta E, but also ensures the long-term accuracy of the absolute value of Color L, A, B, which is convenient for measurement in line with international and national standards at any time. It uses a built-in silicon photodiode array (24 groups in two columns) sensor and imported whiteboard. Repeatability Delta E * ab can be easily controlled within 0.1, taking into account Measurement speed and operation convenience. It can quickly complete color difference measurement and judgment without connecting to a computer.
Features
1. Adopt ergonomic design, smooth appearance, comfortable grip, suitable for continuous inspection work.
2. Adopt full-band Balanced LED light source to ensure sufficient Light spectrum distribution in the visible range, avoid the loss of specific bands, and ensure the measurement speed and accuracy of results.
3. Using a larger area of silicon photodiode array (dual 24 array) Sensor, it has the characteristics of strong light unsaturation, high weak light Sensitivity and wide Light spectrum Response range, ensuring Measurement speed, accuracy, Stability and conformity.
4. Each instrument has been verified and tested, and the measurement data is traced back to the National Measurement Institute to ensure the credibility of the test data.
5. Using imported yellowing-resistant standard whiteboard and innovative ETC real-time calibrating technology, Optical inspection system has built-in standard whiteboard to ensure the accuracy and Repeatability of each test.
Principle
The DS-100 spectroscopic color difference meter adopts D/8 (diffuse illumination, 8 ° direction reception) illumination mode, which meets the relevant Optical inspection standards. The instrument illuminates the sample by combining the full Light spectrum LED light source, uses the plane grating to split the light, and receives the reflected light signal by the silicon photodiode array (24 groups in two columns) Sensor, and analyzes it in the wavelength range of 400~ 700nm. Finally, the color space value (such as CIE LAB) and color difference value of the sample are calculated.
