Goniophotometer Suitable For Mid-To-Large Sized SSL Sources And LED Modules

LGS 650 goniophotometer is built and designed for the analysis of angle-dependent spatial radiation properties from mid- to large-sized SSL sources and LED modules. The LGS 650 is part of the established LGS family and perfect for samples up to max. 1300 mm diameter and 10 kg weight. 

The LGS 650 is compatible with all spectroradiometers supplied by Instrument Systems. The CCD array spectrometers of the CAS series are ideal because they feature a very large dynamic measuring range and very short measuring times. The measurement system is supplemented with optical probes from the EOP series. They are calibrated together with the spectrometer in the ISO 17025 certified laboratories of Instrument Systems. The LGS 650 is compliant with all relevant specifications in conformity with CIE, DIN and IES standards.

The LGS-650 Goniophotometer is a high-precision instrument designed by Instrument Systems for measuring the light distribution properties of lamps, luminaires, and other lighting products. It is a versatile and reliable tool that enables lighting manufacturers to evaluate and optimize the performance of their products.

The LGS-650 Goniophotometer measures the angular distribution of light emitted by a source, enabling users to analyze key parameters such as luminous flux, luminous intensity, and color. The instrument is capable of measuring light at angles ranging from -160 to +160 degrees, with a resolution of 0.01 degrees.

Combined with a spectroradiometer from Instrument Systems, all spectral quantities such as color coordinates, color temperature and even color rendering index can be determined as a function of angle. C-plane measurements can also be carried out very quickly “on-the-fly” using the DSP 10 or DSP 200 Photometer. This provides an overview of the spatial light distribution for the test specimen very quickly. A comprehensive software package facilitates easy evaluation and reporting of the measured data. The measurement results can also be exported in standard file formats like IES and EULUMDAT

One of the key advantages of the LGS-650 Goniophotometer is its high accuracy and repeatability, which enables users to make precise and reliable measurements of light distribution properties. The instrument is also highly flexible, with the ability to accommodate a wide range of different products and testing scenarios.

Overall, the LGS-650 Goniophotometer is a powerful and reliable tool for lighting manufacturers and researchers, providing precise and accurate measurements of light distribution properties. Its flexibility and ease of use make it a valuable tool for a wide range of applications in the lighting industry.
