BTS256-LED Tester
Compact BiTec Spectroradiometer LED Tester for the Measurement of Total Luminous Flux of Single VIS and NIR LEDs


Photometric, temperature stabilized detector with DP-11 mount

  • For use with integrating spheres
  • Operation temperature controlled at 50 °C
  • Photometric responsivity
  • for use with optometers and signal amplifiers

Modular light detectors are designed to be combined with optics and mechanical components to configure complete light detection assemblies for a specific light measurement application. A mechanical interface is provided to make mounting or adding other components easy and flexible.

Photometric Responsivity

The TD-11VL01 detector is compact in size and fit the DP-11 detector port interface of integrating spheres directly or can be mounted to most Gigahertz-Optik integrating spheres using an adapter. The TD-11VL01 offers an accurate CIE V(λ) spectral match. It is most commonly used with integrating spheres for total flux measurements or as monitor detector on integrating sphere light sources.

Temperature Stabilized 

The TD-11VL01 photometric detector features thermo-electric temperature stabilization where the detector is heated up to a controlled operating temperature of 50°C. The most common use for the TD-11VL01 detector is with integrating spheres where housing temperature increases during operation. The control electronics are housed in a separate case and powered by a plug-in power supply.

Traceable Calibration

Optional calibration is available by Gigahertz-Optik’s Calibration Laboratory for Optical Radiation Quantities.
