Screen
Absorbs the ray, so you can see where it lands.
How to add
In the left Instruments and experiments panel, Light and lenses section: click the element and it appears in the centre of the frame. Rays are traced instantly, no need to run the simulation. Place the screen behind the lens or at the end of the ray path.
Properties
- Angle, W and H
- Rotation and size of the screen. By default it is a narrow vertical strip.
Tips
- A screen stops the ray, so there are no rays beyond it.
- Move the screen along the axis to find the position where the beam converges to a point.
