NE^v NEV\^ ^v S'^'*^-^'4 NE\V '^i'lfj/v^^ FOR LIGHTED ROOM PROJECTION Of vital importance to all users of audio-visual aids is this new and different kind of "lenticular" screen surface — the result of more than 7 years research and development work by leading optical engineers and physicists. Actual tests have definitely proven that this surface is extremely effective for projecting in undarkened or even lighted rooms where no extreme or unusual ambient light conditions prevail. RADIANT TESTS PROVE Special electronic testing equipment is used to check the efficiency of all reflective surfaces by Radiant's engineering staff. This equipment measures accurately light gain (brightness), percentage of fall-off, quality of reflection, and other factors vital to good projection results. The new Radiant "lenticular" surface has been subjected to these exacting tests with the following findings: I Radiant "lenticular" Screens showed a very high brightness gain with a minimum of fall-off at sides. 2 Radiant "lenticular" Screens provide increased brightness to an area 45° to each side of axis, thus offering a 90° good viewing area. 3 Radiant "lenticular" screen surface reflects colors with increased vividness and greater contrast.
