CHN SPEC DS-39D Benchtop Spectrophotometer (d/8, 360nm-780nm, XLAV ΔE*ab 0.08)

The CHNSpec DS-39D Benchtop Spectrophotometer is a new generation benchmark-class color measurement device designed to deliver outstanding accuracy in color analysis and control. With an advanced optical sensor system, this instrument meets the most stringent standards in both R&D laboratories and industrial quality control (QC) processes.

Key Features

Differential Spectrum Engine: The self-developed differential engine enhances the input light flux by 50% and increases the spectral resolution by 30%, while providing a better signal-to-noise ratio.

Dual Optical Path Design & Ultra-high Repeatability: The dual optical path design monitors the light source energy fluctuations while measuring the sample signal, reducing interference and improving measurement repeatability to an excellent level of ΔE*ab ≤ 0.005.

Inter-instrument Agreement: Reaches XLAV ΔE*ab ≤ 0.08, ensuring measurement data is always consistent with other international standard measurement systems.

Ultra HD Positioning Camera: Equipped with an observation camera with a resolution of up to 1400dpi, helping users precisely position the measurement point on the sample, which is especially useful for samples with patterns or tiny details.

Versatile Automatic Aperture Switching: The device supports multiple measurement aperture sizes and automatically recognizes them when switched, including: XLAV (Φ30mm), LAV (Φ18mm), MAV (Φ11mm), and SAV (Φ6mm), making it easy to measure samples of various sizes.

Comprehensive Smart Calibration System: Integrates automatic calibration features to maintain long-term stability. Notably, the device features fluorescence calibration that automatically adjusts UV intensity, providing accurate data when measuring materials containing fluorescent substances.
