LED Station - a cost-effective system solution for LED measurements

The LED-Station is a cost-effective system solution for testing LEDs. The system is based on the mini-array spectrometer MAS 40 and is designed for determining the light radiation from LEDs. Different adapters can be attached to the robust input flange of the MAS 40, enabling measurement of both luminous intensity and luminous flux. From a single measurement of the spectrum, additional spectral parameters such as the color coordinates, the color temperature or the dominant wavelength can be calculated.

The MAS 40 can additionally be expanded through attachment of a mini goniophotometer for determining the spatial radiation pattern of LEDs. The LED-720 constant current source (50 mA max.),ideally suited to driving standard and high-brightness LEDs, completes the LED-Station.

All components of the LED-Station correspond to Instrument Systems stringent requirements on quality and performance, and are calibrated together with the spectrometer before shipment.
