LED measurement - Matching accessories for every measurement parameter

Measurement of the various radiometric und photometric quantities of LEDs requires selection of the appropriate accessory. As all our test adapters are CIE 127:2007 compliant, comparability between measurements is guaranteed.

Connection to the spectrometer is made using an optical fiber bundle or a multimode fiber. Accessories can thus be quickly and conveniently swapped simply by disconnecting the fiber, all without losing the calibration of the spectrometer for the respective accessory

The following table gives an overview of the available accessories:  

By utilizing a spectrometer, all colorimetric parameters such as dominant wavelength, color coordinates, color temperature and color rendering index can also be determined in addition to the radiometric und photometric quantities.

Matching test sockets for every type of LED packaging

LEDs are manufactured in a variety of packaging designs and configurations - as wired single LEDs, in SMD format or as multi-chip or high power LEDs. Or even as Level 2 printed-circuit-board based products, as is the case for the Luxeon Star. The test sockets needed for mechanically aligning and electrically connecting LEDs are thus equally diverse in order to ensure reliable optical measurements. Instrument Systems provides the broadest range of mounting accessories available anywhere in the industry.
