Front Projection Lens
The large optical lens at the front is one of the most noticeable parts of the projector. This lens is responsible for directing the projected image toward the wall or screen. Its prominent design allows the projector to concentrate the light and form the picture at a larger size. The lens area also has a manual adjustment mechanism around it, which can be used as part of the process of obtaining a properly focused image. Keeping the lens clean and protected is important because dust, fingerprints, or scratches can affect projected image quality.
