A piece of professional glass is the soul of a teleprompter, so not just any ordinary piece of glass can be used as a teleprompter glass.
Teleprompter beam-splitting glass is a kind of transparent glass lens on the teleprompter, and its thickness is usuall less than 3mm. When using the teleprompter, the text content can be reflected on the display screen, so that the user can see it clearly and complete the “final transmission” of the text content; at the same time, the camera can clearly capture the speaker’s movements and expressions through the glass.
