Key components of the device include a built-in 50mm diameter integrating sphere with a unique interchangeable input optic nozzle designed to minimize positional error, auxiliary LED and GO Bi-Tech sensor.
The integrating sphere is made out of GO's ODM98 white diffuse material and includes a sealed window light output port.
The Bi-Technology BTS256P light sensor houses both a high precision photometric filtered photodiode for accurate flux detection over a wide dynamic range and a compact low stray light design spectrometer.
Another key feature is the ultra compact electronically controlled shutter for on-line offset compensation of the diode array for improved signal to noise levels.
Spectral flux distribution in W/nm as well as peak wavelength, dominant wavelength, xy and u'v' color coordinates, color temperature and color rendering index are measured and displayed. The measured spectral data is also used for on-line correction of the photometric detector for any photopic spectral mismatch error.
To compensate test sample absorbance errors a white LED auxiliary lamp is included. The PC operated LED tester, auxiliary lamp function and calibration correction for different size input nozzles are all under control of the supplied G.O.O.S. software.
The BTS256-LED tester price is $4900-.
