LGS 350 – Perfect for mid-sized SSL light sources and LED modules

The LGS 350 Goniophotometer / Goniospectroradiometer was developed for the analysis of angle-dependent spatial radiation properties from small to medium-sized SSL luminaires and LED modules. The test specimen is operated in a horizontal burning position and measurements can be taken at an angular range of ±160° in the gamma / theta axis.

Combined with a spectroradiometer from Instrument Systems, all spectral quantities such as color coordinates, color temperature and even color rendering index are determined as a function of angle. The Optronik DSP Photometer can also be used to carry out C-plane measurements very quickly “on the fly”.

The complete system

The LGS 350 comprises the goniometer with a sample plate for fixing the test specimen and the LGS Controller that drives the stepper motor and the angle display. If a photometer is used, the LGS Controller also displays the measured values in candela or lux.

The following versions of the LGS 350 are supplied:

Goniometer with stable base and integrated LGS Controller. The structure is particularly space-saving and compact, as well as providing very high mechanical stability with the floor.
Goniometer in benchtop version with separate 19” rack for the LGS Controller. This configuration is mobile and can be used flexibly.

Features

Type C goniophotometer with horizontal optical axis
For samples up to 700 mm diameter and 8 kg weight
Accurate determination of the luminous intensity distribution and luminous flux
Angular-resolved analysis of spectral and colorimetric quantities
Data export in IES and EULUMDAT format
