Studio Extra Wide-angle Trapezoidal Mirror - CCDW / FSW Prompters
WIDE-ANGLE STUDIO MIRROR
B-2002/LR Wide-angle Trapezoidal Studio Mirror for Listec FSW style Hoods.
Coating: 70/30 transmission/reflectance, low-reflectance back coating
All Listec Prompter Mirrors (often referred to as beamsplitters or glass), are manufactured of the highest quality material and coatings—important for HD camera systems, which tend to highlight imperfections.
On par with the need for a quality display and smoothness of scroll, prompter glass is vital to a distortion-free presentation, which translates to a comfort factor for the presenter.
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 studio lighting is well controlled, reflectivity averages 30 percent; for field operation and brightly lit environments, 40 percent reflectivity is usual. In addition, most Listec Mirrors feature a low-reflectance coating on the back side to prevent light penetration through the glass, which could have an effect on auto-sensing of light levels.
Note: Special coatings may be custom ordered.
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!
