The LightSpion Extender® is an excellent addition to your LightSpion. The extender provides you with the distance necessary for measuring light sources that are up to 22 cm in diameter and up to 5 kg in weight.

Manual rotation of the lamp in 45-degree steps (up to 8 c-planes) allows measuring even asymmetrical light sources.

To install the LightSpion Extender just connect the platform to the previously installed LightSpion suitcase through a RJ45 connector. The Light Inspector software then detects the Extender and automatically adjusts the calibration data according to the new setup.

The clamps for mounting the light source can be configured in multiple positions. The Extender platform has two additional measuring distances: At 115 and 182 cm between the light source and the LightSpion sensor.
