The optical probe of the spectroradiometer or the photometer head for taking measurements is placed outside the photometric distance and attached to a stray light tube adjusted to the measuring distance and the sample size. The measuring distance should be 10 to 15 times the diameter of the light source being tested. The goniometer unit The LGS 350 Goniometer rotates the test specimen in the gamma and C axes. The horizontal alignment of the CIE 121-1996 coordinate system facilitates a particularly compact test setup. Both axes can be operated simultaneously and can be moved smoothly and...

within a few minutes. Even pulse-width modulated LEDs with cycle frequencies of 80 Hz to 10 kHz can be measured precisely using the adaptive filtering and digital signal processing of the innovative DSP 10 Photometer. Measurement sequences in SpecWin Pro SpecWin Pro software powers the outstanding productivity of the LGS 350. Two measurement modes are supported. Firstly, the sequence mode allows spatial radiation patterns of the test specimen to be recorded for gamma and C axes in defined angular increments. All measured data are available for subsequent evaluations. Secondly, the test...
