FAQ

HOW DOES PORT WINDOW GLASS CONTRIBUTE OR DETRACT FROM A THEATER-GO-ER’S EXPERIENCE?

Use of a port window insulates the theatergoer from hearing noises from the projection room. The port window also needs to allow maximum pass-through of light in order for the audience to see the full brilliance of digital projection.

WHY NOT JUST LEAVE THE PORT WINDOW OPEN?

Port window glass keeps the projection equipment sound insulated from the auditorium. Many commercial theaters are required to use glass in the port window as per the building code. Home theaters benefit in the same way.

HOW DO THE ANTI-REFLECTIVE COATINGS (AKA A/R COATINGS) ON PORT WINDOW GLASS WORK?

A/R coatings match the photopic reflectance of air, which is called “index matching” in the world of optical coatings. The net effect is nearly invisible glass.

HOW DO I CARE FOR PORT WINDOW GLASS?

OptiClear is impervious to dust and dirt in normal applications. Dusting with a dry soft microfiber cloth is usually sufficient. Heavier contamination can be removed with 70% solution of isopropyl alcohol and water. Gently wipe the glass before the alcohol dries. Do not use regular paper towels or newsprint as these may contain grit. Avoid harsh cleaners containing ammonia. For more information look at our cleaning guide
