Introduction

As the standard appliance in color measurement, this set is based on the chromaticity of three primary colors for the development. Using color glazed porcelain blocks after special fired processes.

Features

Smooth surface, Uniform color, High color saturation.

Stable optical and physical properties.

Cover full visible light ‘s spectral wavelength.

Specification

1. Color coverage: Red, Yellow, Green, Blue, White. This set covers full spectral wavelengths of visible light(380nm~780nm). 

2.  Weather resistance:Manufacture of high temperature colored glaze. Better weather resistance, no cracking, no falling off. Stable color, Dx and Dy of each point are<0.001.

3.  Optical property:Annual gradient Dx and Dy are<0.002 (National standard is<0.005). After one year's illumination test, the chroma value has no obvious change with has better illumination resistance. 

4.  Surface feature:Smooth surface, uniform color. Good surface hardness. Lighttight, no cracks, no wrinkles, no bubbles and other defects.

5.  Dimension:50mm*50mm*10mm(each unit)
