Data sheet We bring quality to light. Product highlights Type C goniophotometer for large SSL luminaires and LED modules up to 1900 mm in length Accessible steps facilitate mounting of samples Accurate determination of luminous intensity and luminous flux Angular-resolved analysis of spectral and colorimetric quantities Data export in IES and EULUMDAT format The LGS 1000 is the latest product in a new family of goniophotometers and goniospectroradiometers manufactured by Instrument Systems. It has been developed specifically for the analysis of angle-dependent photometric and colorimetric properties of large SSL luminaires and LED modules and can accommodate specimens up to a length of 1900 mm and a maximum weight of 50 kg. This is also reflected in the dimensions of the machine of 1850 x 1492 x 1798 mm (H x W x D). The specimen can be rotated in an angular range of ±165° in the Gamma axis and ±180° in C axis. Combined with a spectroradiometer from Instrument Systems, all spectral quantities such as color coordinates or color temperature can be determined as a function of angle. C-plane measurements can also be carried out very quickly “on the fly” using the Optronik DSP Photometer. This provides an overview of the spatial light distribution for the test specimen very quickly. Spectral software SpecWin Pro allows measured data to be processed and displayed, e.g. as an Isocandela diagram. The measured data can also be exported in standard file formats. light measurement

We bring quality to light. The complete system The LGS 1000 comprises the goniometer with a sample plate for fixing the test specimen and the LGS Controller that drives the servo motor and the angle display. If a photometer is used, the controller also displays the measured values in candela or lux. The complete system comprises the components: Accessible steps to goniometer with stable base enable test specimens to be easily mounted LGS Controller in 19” rack 33 U in height (approx. 165 cm) The goniometer The LGS 1000 Goniometer rotates the test specimen in the gamma and C axes, or theta and...
