Our Clusterpartner Gigahertz-Optik expands its successful BTS256-LED tester product line with two new versions: the BTS256-LED-UV and BTS256-LED-IR. These portable, compact measuring devices, equipped with the proven "BiTec Sensor" system, are specially designed for precise measurement of UV and IR LEDs. Like the standard model for photometric, colorimetric, and spectral radiometric testing in the visible range, the new testers also feature an integrated integrating sphere with a conical measurement port. This allows LEDs on circuit boards to be tested both in handheld operation and in fixed setups. The devices measure radiant power, spectral power distribution (SPD), peak intensity, and other parameters.
An additional UV or IR auxiliary LED for absorption correction, typically only found in stationary LED measurement systems, enables even more precise measurements—controlled via the included software. This makes the new testers ideal for applications in quality assurance, research and development, as well as production monitoring.
Technical specifications of the new models
BTS256-LED-UV: Calibrated spectral range from 200 to 550 nm, optical bandwidth of 5 nm (CIE 214 correction). Radiant power measurement range from 10 µW to 2 W (typical for a 350 nm LED).
BTS256-LED-IR: Calibrated spectral range from 750 to 1100 nm, optical bandwidth of 5 nm (CIE 214 correction). Radiant power measurement range from 0.3 µW to 5 W (typical for a 900 nm LED).
The control and evaluation are fully managed via the S-BTS256 software, which offers all key functions such as integration time, mathematical corrections, and measurement parameters.
Traceable Calibration in the In-House ISO/IEC 17025 Laboratory
The BTS256-LED testers are calibrated in Gigahertz-Optik's ISO/IEC 17025 accredited calibration laboratory. Two calibrations ensure maximum precision: A specially designed reference lamp with 2pi emission is used for the accurate measurement of diffusely emitting LEDs. The second calibration is tailored for narrow-beam light sources.
Versatile Use in the Visible Spectral Range
For photometric, colorimetric, and radiometric measurements in the visible range, we recommend our BTS256-LED Plus concept, which extends the functionality of the tester for a wide range of applications.
