The OCRL-5000 Luminance Spectrophotometer is a portable instrument integrating spectral, luminance, and colorimetric measurement functions. It features a compact Czerny-Turner optical design and a 2048-element linear CCD array, providing spectral and colorimetric analysis for light sources, displays, panels, and other light-emitting devices.
The OCRL-5000 provides a spectral measurement range of 380–1000 nm with a spectral resolution of 0.5 nm. Equipped with a 10 mm optical input aperture, it supports a luminance measurement range of 5–15,000 nits. In addition to spectral response, the instrument measures luminance (Lv), correlated color temperature (CCT), color rendering index (CRI), peak wavelength, dominant wavelength, radiance, CIE 1931 (x, y), CIE 1976 (u′, v′), XYZ tristimulus values, color gamut, and other photometric and colorimetric parameters.
The instrument is equipped with a 5-inch color LCD touchscreen for direct operation and measurement display. It also supports USB data transfer and PC measurement and control software for data acquisition, storage, and analysis.
