A Navitar ScreenStar is a conversion lens for video projectors. It is simply placed in front of the projector's standard lens allowing users to easily change the picture size or throw distance for almost any size format video projector. If needed, slide the ScreenStar from left to right to capture the four corners of the projected image.
To enlarge your image size, rotate the projector zoom lens to wide angle and use this 0.65x ScreenStar wide angle conversion lens to increase your image by 20-50% from the same projection distance.
