Lighting test bench accessories

This pack, intended for use with the 4 lighting systems bench, is composed of two accessories:

- Angular distribution accessory:
A laminated and graduated A2 sheet, with markings every 10 degrees to accurately and easily trace the angular distribution of the illumination.
Alignment of the considered source with the protractor's zero is facilitated by the 2 markers.
This accessory includes a linear marker graduated every 5 cm for precise measurements.

- Point source accessory:
Thick cardboard protection with a front opening.
Tracing the evolution of illumination based on distance, regardless of the position of the lamp considered, is then very easy.
