# Mirror

Mirrors can be placed within an optical space to reflect light beams and rays.

Tips for use:

- There are 'hotspots' at important points on the mirror. Measurement parts such as the ruler will snap to these hotspots to let you measure key lengths.
- Use the resize handle in-scene to change the radii of the convex and concave mirrors.
