Measured value
for LEDs


BTS256-LED-IB for the measurement of “Average LED Intensity” ILED-B according CIE Dokument 127 with the BTS256-LED The BTS256-LED-IB adapter is used to enhance the measurement functions of the BTS256-LED making it possible to measure the averaged LED intensity. The integrating sphere of the BTS256-LED ensures high responsivity homogeneity levels over the 1cm² measurement surface. The LED tester, with its Bi-Technology sensor, ensures precise measurement of the averaged LED intensity, luminous flux, spectral radiant power, color temperature, Ra and R1 to R15 color rendering index, xy and u’v’. The BTS256-LED is a high-quality light meter for measurement of the luminous flux, luminous spectrum and luminous color of LEDs in the visible spectral range. BiTec light sensor for complex light measurement One of the characteristic properties of the mobile light meter is its BiTec light sensor. This combines the characteristic properties of a silicon photodiode with those of a low-noise CMOS diode array. The BiTec sensor guarantees precise photometric, spectral-radiometric and colorimetric measurement values over a large dynamic range through mutual correction of the measurement signals of both sensors. Silicon photodiode detector, fast and linear When taking into account the dynamic range, linearity and speed, silicon photodiodes have always been and are still the ultimate radiation detectors. A silicon photodiode is therefore incorporated in the BiTec light sensor of the BTS256-LED Tester. Its precise matching to the photometric V(λ) CIE responsivity is also ideal for LEDs due to the integration of the diode array’s spectral measurement data.
