LED Light Meter, Integrating Sphere, 21cm Diameter
Manufacturer's part number :
BTS256-LED + ISD-21-V01
The BTS256-LED is high-quality light meter for measurement of the luminous flux, luminous spectrum and luminous color of LEDs in the visible spectral range. The optional IDS-21 integrating sphere expand the application range by making it possible to measure the luminous flux of spot sources with diameters of up to 63.5mm.
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.
