Abstract
NON-REFLECTING windows are beginning to be used for shops. The reflectionless window is a British invention. It is made of a concave sheet of glass so constructed that the light from all sources incident on it is reflected to two black boards arranged one at the top and one at the bottom of the glass. The eye of the observer looking at the glass from in front is completely unaffected by any of the reflected light, the result being that it is very difficult to believe that there is any glass between the objects displayed and the observer. The prospective buyer therefore views the goods more clearly and is not distracted by images. It is also claimed that the reflectionless window effects an appreciable saving in the cost of artificiable lighting, since every lamp in use is able to give its full illuminating value and has not to compete with the disturbing effects of outside rays reflected by the window. The new window is applicable to all shops whether new or old, and for maintenance it costs no more than an ordinary plate-glass window. An illustrated description of the reflection less window is given in the Illuminating Engineer of January, 1934.
