Single lens as a projector

The Lens Equation tells us that the image is not formed anywhere - its position depends on the position of the object and the focal length of the lens:
1/f' = 1/s₁ + 1/s₂
The magnification is given by
M = h₂/h₁ = s₂/s₁
When using a lens as a projecor, the image is always inverted, magnified and real.

The projector is also a part of the SimpleBOX. Find out more about in the SimpleBOX manuals
