PROMPT / AUTOCUE / PEPPERS GHOST GLASSES
Titanium is a high quality, permanent, semi-reflective layer. The standard beam splitter (50:50) is used at an angle of about 45°.At exactly 45° the reflection is a few percent less than the transmission. An angle of about 50° is needed for a precise 50:50 split. It allows images from two directions to be combined into one. Used in another configuration it allows images to be projected and re-photographed, filmed, videoed etc. A second standard coating ratio (30:70) is available; this reflects one third (see diagram image 2) and passes two thirds of the direct image (see diagram image 1). This is the normal standard for prompt and autocue glasses.Because it is baked on to the glass at a temperature of 400 degrees C it cannot wear away and may be cleaned and treated as a normal glass surface.


Normal range of thickness
The titanium coat is normally used on 2mm (or less) glass thickness, for beam splitters below 6" square. Larger than about 6"- 8" (150-200mm ) upwards, 3mm glass is the standard used on most autocue and prompt glasses.

Normal size range
This is from one eigth inch square (3 x 3mm) up to 28 1/2" x 36" (725 x 915mm) rectangles, this largest size is normally 4mm or 6mm glass.
