The Benchtop Spectrophotometer is a precision colour measurement instrument designed for accurate colour analysis, comparison and quality control across various materials and products. It uses an advanced 256-image-element double-array CMOS image sensor and a combined LED light source to provide reliable reflectance and transmittance measurements. The instrument supports multiple colour spaces, international colour difference formulas and standard illuminants for comprehensive colour evaluation. With its integrating sphere design and multiple measuring aperture options, it is suitable for laboratories, manufacturing industries, research facilities and quality control applications.
