We have developed the TFCT25 transmission measurement setup with one main application in mind:
the measurement of a light guide’s transmission properties. A number of elements are required in order to fulfill this task:
Sample holders with magnetic bases allow the flexible positioning of light guides with complex shapes while still allowing their stable fixture.
A magnetic steel table top is recommended for their use.
This article will first describe the requirements of LED/SSL (LED = light emitting diode, SSL = solid state lighting) testing and the possible metrological solutions for different applications, ranging from applications in the production field and laboratory measurements, to on-site tests by users/customers. Gigahertz-Optik has over 30 years of experience in light measurement technology, and has taken a very innovative path in spectral measurement with the BTS technology.
