Therefore, the need for top-performing spectrometers in industrial or large-scale laboratory settings has by no means diminished. In response to this particular need, GL OPTIC has developed a robust, laboratory-grade product designed for large-scale applications: the GL SPECTIS 6.0.
It comes in a 2U 19" rack enclosure (480 x 262 x 88.9 mm) that can be easily integrated into a standard data cabinet and supports measurements across a broad spectral range of 200 nm to 1050 nm, spanning from ultraviolet (UV) through the visible (VIS) range to near-infrared (NIR), offering a high resolution of 3.5 nm. This high-end spectrometer is specifically designed to meet the demands of production process control in the manufacturing of LED chips or lamps and adheres to the requirements of increasingly stringent international lighting standards, such as CIE 127:2007 for LED measurements, which defines techniques for evaluating photometric and radiometric quantities such as total radiant flux or partial LED flux, and IESNA LM-79-08, which describes procedures for performing reproducible measurements of total luminous flux, luminous intensity distribution, or chromaticity of SSL products.
The SPECTIS 6.0 also complies with the ecodesign requirements for LEDs in accordance with EU Regulation No. 1194/2012, which enforces minimum efficiency levels and labelling requirements for LED packaging. Another key feature of LED lighting is energy efficiency, which is often compared to conventional lighting sources. This is typically characterized using luminous efficacy (measured in lm/W) and is determined by quantifying the spectral characteristics of the respective light elements, primarily based on luminous flux and radiant power. These measurements can be performed by coupling the spectrometer with an integrating sphere.
