Source Types

This page describes the different types of sources available when designing an optical surface.

The source corresponds to the source that is used to illuminate the optical surface. In the interface, 2 types of sources are available.

A Punctual source is a simplified source that emits light from a single point and position.
An Extended source is used to emit light from a surface. To use this option, a source geometry (like a light bulb, LED, surface) must already exist or be created.
With an extended source, the source images are available in the feature viewer.

Example of extended sources:
