Cm-2600d sets are simple, comfortable, intuitive and highly sophisticated, patented, innovative optical systems capable of achieving colour measurements in quality control for almost all applications. The innovation was initially introduced by the desktop spectrometric cm-3600d series, which is embedded in a d/8° gestation ball and includes digital light control and is now available in portable, digitalized uv controls. The entire optical system consists of high-energy arc lighting and a high-resolution integrated double-beam monochrome, which does not contain any active components and therefore has a good durability and reliability。
