Corning would like to submit a paper for publication
relating to rear view screens. It would be for the April, 1968
issue of "Applied Optics" which will be devoted to the Company.
An abstract of the paper, which is written by ~ STAT
is enclosed. The paper itself has not yet been com- STAT

PREDICTING THE OPTICAL PROPERTIES OF IMPROVED

Corning, New York 14830
The Mie Theory of light scattering is used to theoretically
determine the relations linking the optical viewing properties
such as axial gain, brightness, uniformity, efficiency, color
fidelity and sensitivity to ambient light with the physical
properties of the material, e.g., particle size, number
density, and relative refractive index of the scattering
particles.
From basic light-scattering data, all other optical properties
are computed, including trade-offs required for different view-
ing requirements. Data from experimental investigations are
given for a variety of volume scattering materials made by
Corning Glass Works, to establish the validity of the theor
etical calculations. The data also indicates that commercial
rear projection screen materials do not exhibit the near-
optimum performance of the Corning materials.
