Light source connection
The measured light source is connected using an all-purpose power connector placed
on the back of the goniometer base, as shown below.

Making measurements
The LightSpion Extender measurements are done in the exact same way as in the
case of LightSpion.
Please refer to the LightSpion user manual for further details.
When measuring linear tubes, their width should not exceed half of the maximum
diameter of light sources for the Extender, namely 220 cm. That means the
maximum width of the tubes is 110 cm.

Stray Light Corrections
Sometimes when measuring specific light sources,
you can observe reflections in the black surface of
the extender plate, adding to the amount of light
detected by the sensor. Such an example is shown
in the picture to the right:
To avoid the unnecessary the false light /stray
light, remember to use the Straylight Plate in the
long configuration.
Also follow instructions in the Viso guidelines
