Large Aperture Spectrocolorimeter BKH-701
Large Aperture Spectrocolorimeter
It is a large aperture spectrocolorimeter that adopts D/8 illumination geometry, with 50mm large test aperture, specialized in color measurement and color comparison of non-transparent materials such as powder, masterbatches and so on. The spectrocolorimeter not only has various color spaces and color difference formulas, but also can display spectral...
Key Features
- 50mm large aperture
- Measuring aperture up to 50mm, especially suitable for color difference measurement of objects with rough surfaces such as masterbatches, powders and rough fabric.
- Display of spectral reflectance curves
- Using full-spectrum LED light source and advanced spectral sensors to provide professional spectral reflectance curves, providing more professional color data for color measurement, from which information such as hue, saturation, depth, etc. can be obtained.
