Used in other configurations it allows images to be projected and re-photographed, filmed, videoed and allows on-axis lighting for photography. This would be important for 3D Camera Devices. With high contrast light and dark tones, the very best result will be obtained with a strongly reflecting glass having an anti-reflective coated rear face. Where the user has control over the lighting, the exact split between reflection and transmission is not too important.Ī greater consideration is the types of images being combined. When used as a 'Peppers Ghost Glass' it allows images from two directions to be combined into one.

In this case the reflection can be increased to the 35% plus mark, as the slight neutral tint of the glass does not detract from its use. Other uses are for Conference Glasses, where a camera is not involved. This reduces the faint secondary reflection even further.Īutocue glasses are usually referred to as having a 30:70 ratio, or 35:65 ratio, indicating the relative amounts of light being reflected and/or passed to the camera. Some manufacturers of studio equipment use standard glasses, others offer a glass with an anti-reflective coating on the rear surface. The titanium coating absorbs some light and the glass itself about 5% more, so the secondary reflection is greatly reduced.

The secondary reflection from the back surface is faint and unobtrusive for most uses. This ensures a bright image reaches the camera. The strongest reflection available with this coating is about 40%.Īutocue machines usually work with a glass reflecting about 30% of light.

Clear un-coated glass will usually reflect about 15% of light at this angle. The density and therefore the strength of reflection can be varied within a certain range during coating. Normally the glass is used at an angle of about 45°. Reflection level increases the greater the angle. The amount of reflected light varies with the angle of reflection. After coating in the vacuum chamber the glass is fired to 400C to oxidise the titanium metal and produce a tough, transparent, semi-reflective layer. The standard glass uses a high quality, permanent, semi-reflective titanium layer. To see the video click on the image aboveĪutocue / Beamsplitter / Tele-Prompt / Peppers Ghost Glass information
