THE TRANS-LUX WIDE-ANGLE LENS is what makes this type of rear projection possible. Designed to give a lzl

ratio in screen width to lens distance from the screen, the lens also contains a special optical system so that a mirror image is proiected on the screen, but, of course, seen correctly by the audience out front. In this manner,

no special proiection equipment is needed, the machines being operated entirely in quite the orthodox manner.

picture screen-it is transluscent instead of opaque, and is especially designed for rear projection. The picture coming from behind the Trans-Lux screen penetrates through to the front surface and appears there sharply defined and with an illusion of depth. This means that no matter where you are sitting in the theatre, the picture is without distortion or fadeway, so that front seats and boxes are all good seats.

The Trans-Lux screen is made in standard sizes, up to 18 feet wide, entirely in one piece without seams. It is stretched tightly on a frame and remains tight in all kinds of weather. It is shipped to the theatre rolled and is mounted at the job on a permanent frame installed in the theatre.

Owing to the clear definition and depth of the picture, the 12 x 15 foot screen is said to be large enough for a theatre

THE TRANS-LUX SYSTEM is adapted to a wide variety of locations, with outdoor theatres being a natural. In this sketch is seen one such idea. In such shells, there is usually sufficient space to install a Trans-Lux proiectian room, and, if not, such space can be conveniently added. Thus the proiect becomes broadened in amusement scope, to include motion pictures, no less than stage spectacles, operas, symphony orchestras, and even large civic affairs.

with a seating capacity of about 2,000 persons.

If the stage is equipped f0r vaudeville performances, the screen can be swung into the fiy loft and replaced without any loss of time.

With this daylight screen, the theatre can be lighted to any degree the individual manager may decide his patrons like best. The most effective amount of light is that which permits the patron to read a program and does away with the necessity of the ushers carrying flashlights.

Color movies are particularly brilliant on the Trans-Lux screen, giving the impression of a beautiful painting rather than a projected picture.

The first Trans-Lux rear-projection screen was perfected just in time to be installed at the Roxy Theatre in New York for the opening night, March 11, 1927. This screen was 18 x 22 feet.


The Wide-Angle Lens

To obtain a lens which gave perfect definition and passed sufficient light required years of study, and it was only during the latter part of 1929 that the scientific difficulties were finally overcome.

The Trans-Lux wide-angle lens makes possible the projection of a picture from behind the screen. It also makes a picture possible with only one foot behind the screen for every foot of width of picture. That is, a 15-foot picture requires only 15 feet from lens to the screen. Using an ordinary projection lens, about three and a half times this distance would be required, or about 53 feet, which, of course, would be impracticable on an ordinary stage.

Furthermore, the Trans-Lux contains a special prism which reverses the picture without having to reverse the filmstandard projectors and sound heads can be usedethe regular film from the exchanges is threaded through the projectors in the usual way.

The two projectors are placed so that the lenses are only 12 inches apart and on a level With the center of the screen. This arrangement eliminates keystone and distortion of the picture which is present in front projection where the booth is in the balcony.

Proiection Room

Except for the special placing of the projectors and the lenses, the booth is entirely standard as to equipment and operation.

The projectors are placed at an angle of 90 degrees to each other so that they require less depth of booth than is ordinarily the case.

This arrangement provides ample room for the efficient operation of the machines in addition to the saving of space.


There are many locations where it is practical and expedient to build a TransLux theatre entirely in the open air, at low cost for construction, at considerable saving in operating expense. This is particularly so where a grove of trees or a roof Offers some measure of protection from the direct rays of the sun.

In gardens, where refreshments are served, a Trans-Lux theatre may prove to be an attraction which will greatly increase profits.

In warm climates, where the cost of cooling an ordinary theatre has been a

' problem, Trans-Lux makes possible an

outd00r theatre at a minimum cost.

As for television, the Trans-Lux screen and equipment is adaptable to this type of picture. The company is in a position to turn out as much of this equipment as is necessary, and is looking forward to serving this new industry.

There is, indeed, a large field for the Trans-Lux rear-projection system, not only for motion-picture theatres, but also in many and varied branches of the motion picture industry, the fourth largest industry in the world. With rear-projection, the public is offered better and softer motion pictures, as well as greater comfort, ease, and safety in the enjoyment of this most universal form of modern recreation.
