The growing number of quality requirements introduced by new standards for lighting has made it necessary to ensure constant control of LED products as they are being produced. In the realm of LED measurement and testing, a lot of attention has as of late been given to the development of small, handy size devices, allowing for the quick and easy assessment of any light source. Yet the need for top performing spectrometers in industrial or extensive laboratory settings has by no means diminished. It is in response to this particular need that GL OPTIC has developed a robust, laboratory-grade product engineered for large scale purposes: the GL SPECTIS 6.0.
It comes in a rack-mountable 2U 19” housing (480 x 262 x 88.9 mm) which can be easily integrated into a standard data cabinet and supports measurements in a wide spectral range of 200 nm to 1050 nm, spanning from ultraviolet (UV) through visible range (VIS) to near infrared (NIR), offering a high resolution of 3.5 nm. The high-end spectrometer is specifically designed to meet the demands of production process control in the manufacture of LED chips or lamps and adheres to the requirements of ever more strict international lighting standards, such as CIE 127:2007 for LED measurements which defines techniques for assessing photometric and radiometric quantities such as total radiant flux or partial LED flux or IESNA LM-79-08 which describes procedures to perform reproducible measurements of total luminous flux, luminous intensity distribution or chromaticity of SSL products. The SPECTIS 6.0 also meets the ecodesign requirements for LEDs in accordance with EU Commission Regulation no. 1194/2012 which enforces minimum efficiency levels and labelling requirements of LED packaging. Another key characteristic of LED lighting is the issue of energy efficiency which is often compared to conventional light sources. This is typically characterized using luminous efficacy (measured in [lm/W]) and is determined by quantifying spectral characteristics of respective luminous elements assessed mainly on the basis of luminous flux and radiant power. These measurements can be made by coupling the spectrometer with an integrating sphere. All in all, the high-end GL SPECTIS 6.0 will optimally meet the development and quality assurance needs of lamp manufacturers, as well scientific institutes, consultants, material researchers, and many other user groups.
