All Listec Prompter Mirrors (often referred to as beamsplitters or glass), are manufactured of the highest quality material and coatings.
On par with the need for a quality display and smoothness of scroll, prompter glass is vital to a distortion-free presentation, making it more restful on the eyes of the presenter; it is also important for HD camera systems, which tend to highlight any imperfections.
A beamsplitter is rated for transmission and reflectivity, which affects f-stop loss vis-à-vis the lens. The greater the reflectivity, the less through-the-glass transmission there is. Generally, because TV studio lighting is well regulated, reflectivity averages 30 percent; however, for small studios, and when lighting cannot always be controlled, 40 percent reflectivity is usual.
CAUTION: Mirrors should be cleaned with an anti-reflectance solution, as used for non-reflective eye-glass lenses, or two-parts water to one part alcohol. Strong ammoniated solutions should be avoided!
