A movie projector uses a convex lens to focus and magnify the light and image projected onto a screen. The convex lens converges the light rays from the film, creating a clear and sharp image at a larger scale. This type of lens is essential for ensuring that the projected image maintains detail and brightness, allowing for an optimal viewing experience.

When a movie projector is moved closer to the screen does the image get smaller or bigger?
Assuming that the lens is not adjusted, the picture will become smaller as the projector is moved towards the screen. The size of the picture is related quite precisely to the distance, so moving the projector to half the distance will result in an image half the width and half the height. This applies to projectors of all types, not just movie projectors. Most video and some movie projectors have zoom lenses so the image size can be adjusted without moving the projector. Alternatively, if the projector is moved, the lens can be adjusted to restore the original image size (within certain limits).

Look for a lens with a suitable focal length that matches your projection setup, typically around 10-20 inches for small projects. Ensure the lens has a high-quality optical clarity to minimize distortion. Finally, consider the lens size and shape to fit your projector design and housing.
