Projection & View Ports
The quality of the projected image is, obviously, one of the most critical concerns of any movie theater operator, as is the acoustic isolation between the projection booth and the auditorium. Your investment in a superior Goldberg Brothers projection port helps you make sure that what your audience sees and hears is what the filmmakers intended.
We make projection and view ports in a wide range of standard sizes and designs. We also make custom ports for “multi-projectors” – multi-media projection systems for museums and other venues. Contact one of our industrial products distributors near you and they will help you place a custom order.
Double Glass Projection Port
Our double glass projection frame accommodates two 15″ x 28″ glass panels, each tilted outward by 5-degrees to minimize standing sound waves between panels and to reduce light reflection back to the projector lens.
The booth sides of the port has a hinged frame and safety straps to securely hold the glass in the opened position while cleaning.
All glass and frames have rubber gaskets for excellent air and sound isolation and vibration damping. The glass is available as an option with or without anti-reflective coating.
