Description :

The BTS256-LED is high quality light meter with integrating sphere for the luminous flux measurement of individual light emitting diodes up to 800 lm in the visible spectral range. 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.

The integrating sphere with conical shaped entrance port of the LED Tester enables explicit capture of all the irradiated light from the LEDs independent of their emission characteristics. The cone adapter is placed over the LED for measurement of assembled LEDs. The auxiliary lamp of the BTS256-LED Tester helps compensate for any measurement errors that might result from light absorption on the test LED.
