Medium to long focal length imaging film:

The difference between the telephoto lens anti light screen and other anti light screens in the optical imaging film of the medium telephoto lens machine under forward projection is significant. Its anti light principle is to use a special metal coating to make the surface texture of the screen very delicate, close to a mirror, so as to directionally reflect more light from the projector and improve brightness gain.

　Advantages of medium to long focal length imaging film:

The rear projection optical imaging film can maintain clear imaging while allowing the audience to see a clear image from the front without being able to see the projector. The image quality is clear and bright, and it is widely used in exhibition halls and shopping malls.

Significantly wide, with a maximum width of 1.8M and an infinite length
