Projection lens
The projection lens is the 'image magnification core' of a projection system. Its core function is to magnify the tiny pixel array on the image source through optical refraction and precisely project it onto the screen, forming a clear and regular large-size image. It differs from ordinary imaging lenses; it is a 'reverse optical process from a tiny source to a large-area image', directly determining the size, clarity, and flexibility of the projection image to adapt to space. The projection lens works on the principle of 'lens magnification imaging' and must deeply match the pixel accuracy of the image source. Projection lenses include the following types: ultra-short-throw projection lenses, fixed-focus projection lenses, shaped projection lenses, etc.
