When using a projector, we sometimes encounter situations where the size of the projected image is not ideal, which really affects the viewing experience. In fact, there are two effective solutions.
One is to replace the lens. The focal length of the projector lens determines the image size and the projection distance. If the current image is too small, a short – focal – length lens can be used. Under the same projection distance, a larger image can be projected. If the image is too large, a long – focal – length lens can make the image smaller to meet the space requirements.
The other is to install a front – mounted lens. By installing a specific front – mounted lens in front of the original lens, the light propagation path is changed, thus adjusting the image size. This method is relatively simple and has a lower cost, without the need for complex equipment replacement operations.
Whether it is replacing the lens or installing a front – mounted lens, the size of the projected image can be flexibly adjusted according to actual needs, allowing us to easily obtain the ideal viewing size and enjoy a better visual feast.
