Next-Level Luminance Measurement – Developed with LMT

Building on decades of expertise in screen photometry and the renowned BV Room system, TechnoTeam — together with LMT Lichtmesstechnik — has developed a camera-based screen goniophotometry system that merges the precision of imaging photometry with the standard compliance of classical goniophotometers. The result: complete LID (Luminous Intensity Distribution) measurements in just minutes.

From automotive headlights (including ADB and matrix LED systems) to general lighting applications, this patented hybrid solution is engineered for unmatched speed, accuracy, and flexibility.

How Screen Goniophotometry works

Unlike conventional systems that require slow, sequential photometer scans, the screen goniophotometer uses a precisely calibrated reflective screen in combination with an LMK imaging luminance measurement camera. The device under test (DUT) rotates around two axes within the LMT goniometer, while the LMK captures the spatial light distribution in one or a few exposures. Advanced software automatically stitches multiple image sections into a complete Luminous Intensity Distribution (LID) map, using reference points to ensure high geometrical accuracy.

The Best of Two Worlds

  • 100 times faster than standard goniophotometry
  • Fast pulse width modulation mode
  • Sensor fusion
  • More than 100 installation worldwide
  • Patented technology

Positioning Systems

Depending on the requirements for the movement range and the weight of the test specimens, you can choose from a large selection of precise handling systems.

Sensors & accessories

With a wide range of sensors and accessories, your measurement laboratory can be customized to your exact requirements and needs. Both cooperation partners contribute their core competencies here, so that you can carry out fast, precise and standard-compliant measurements.

Software

The combination of a 2D handling system with an imaging luminance measurement camera makes it possible to assemble a series of camera images, each containing a different section of the light distribution curve of the test specimen, into a complete LID. Various software add-ons are available to meet individual customer requirements.

Depending on the solution, different software packages are available:
