VL-1101 with PD-11Z-01 Front Lens Adapter
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 Detector for use with Compact Integrating Spheres

The VL-11 series detectors with a diameter of only 11mm are compact in size and fit the DP-11 interface directly or can be mounted to most Gigahertz-Optik integrating spheres using an adapter.

The VL-1101 is a modular photometric detector with 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.

Front Lens Adapter for Luminance Measurements

The application range of the VL-1101 detector can be extended for luminance measurement using the add-on PD-11Z-01 front lens.

Temperature Stabilized Light Detector

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.
