Cleaning Projector Glass
For the operator of a movie theater, one of the most important factors is the quality of the projected image. Good projection glass in the port ensure that the audience sees exactly what the filmmakers intended for them to, and not something that got diminished because of a below par projection setup.
Projection glass and view ports come in a wide range of designs and standards. These days, you even get custom-made ports for projectors that integrated with multi-media projection systems. The latter are used in many venues, including museums. Industrial demand for this kind of thing has only gone up, especially since digital projectors came out. Before then, port windows were easier to overlook, because there was no need for advanced technology to be employed in that area.
It is important to maintain superior projection quality in theater projection glass, because this ensures maximum transmission and onscreen contrast. Also beneficial is the fact that color rendering stays optimal. There are many coatings that can ensure good results, but choosing one requires careful review of the optical needs.
Maintaining Projector Glass
If the glass screen has no surface coating on the front, you will need to clean it with a 25% solution of hard-surface cleaner. If the screen has projection glass coating, it is important to check the manufacturer’s recommendations before you proceed. Coatings vary significantly with the brand, which is why you need to use precise and proper cleaning materials so as to prevent damage. Depending on the different plastics, coatings, or textures that the screen material includes, there will be chemicals which it should not come into contact with.
Glass and acrylic based projector screens need more careful treatment than most. With glass bead projector screens, you will need to use dry microfiber, likely frequently. The problem with this type of screen is that you cannot use a cleaning solution instead, but harder projector screen made out of glass or acrylic can handle this. You can use water and mild soap, but the cloth used to wipe this must be free of lint. Also, ensure that you get rid of any moisture on the cloth before using it on the surface.
These are some basics about port window glass, and how some of the types need to be maintained. Once again, consult the recommendations from the manufacturer before you proceed.
