CS-801 Reflectance Spectrophotometer

CS-801 is a high performance color spectrophotometer with sideward test aperture. It could be widely used for printing, textile, plastic, food, medicine, automobile industries to meet customers’ color measurement requirement.

Color spectrophotometer CS-801 adopts geometric of D/8 which is highly recommend by CIE, integration of the full band LED composite light source, double beam optical system, ETC every-test calibration technology, spectral reflectance standard deviation within 0.08, maximum of chromaticity values ΔE*ab is 0.03.

Brief Introduction

1. Its test aperture is in the sideward which makes it more convenient to fix the sample. Solid samples (plastic sheet, cloth) can be placed directly on the test aperture. Paste objects can be placed in a glass cell/cuvette,and then placed in the measurement port. It is very suitable for powder material measurement in case of material falling into the integrating sphere.

2. D\8 Geometry

It adopts internationally agreed geometry D/8 (Diffused illumination, 8 degrees observer) and SCI(specular component included)/SCE(specular component excluded).
