The SD-500 is a high-precision portable grating spectrophotometer for professional color measurement, color matching and quality control. It features d/8 geometry with simultaneous SCI/SCE measurement, a 400–700 nm spectral range, customisable aperture options and camera-assisted positioning.
The SD-500 is a high-precision portable grating spectrophotometer for professional color measurement, color matching and quality control. It combines d/8 optical geometry, simultaneous SCI/SCE measurement, a 400–700 nm spectral range and a choice of 8 mm, 4 mm or 1 × 3 mm measurement aperture configurations. Camera-assisted positioning, a 3.5-inch capacitive touchscreen, USB and Bluetooth 5.0 connectivity and extensive color-analysis functions make it suitable for laboratory, production and field measurement.
Designed for industrial color control where repeatability and consistent color data matter, the SD-500 measures spectral reflectance across the visible 400–700 nm range and calculates a broad set of standard colorimetric values. Its d/8 optical system measures both specular-component-included (SCI) and specular-component-excluded (SCE) data, allowing users to evaluate intrinsic color as well as the influence of surface appearance.
The concave-grating spectrophotometric system and 256-element dual-array CMOS image sensor provide detailed spectral measurement. The touchscreen displays spectral data, chromaticity values, color differences, PASS/FAIL results and color offset information, while the integrated camera assists precise positioning. USB and Bluetooth 5.0 support data transfer and software-based color workflows.
A configurable measurement aperture lets you specify the instrument for larger conventional sample areas or much smaller measurement areas, including a 1 × 3 mm option. This is especially useful for flat, small, narrow or difficult sample geometries. Select the required aperture configuration when ordering.
The SD-500 is intended for precision color measurement, color matching, color communication and production quality control.
