This report summarizes the light scattering properties of many more Corning
Glass Works' materials. Of the 65 samples measured, 5 were found which have
sufficiently good optical properties to warrant further investigations.
Prototype rear projection screens measuring 3" x 3" have been fabricated from
Fotoform? glass. Work is continuing on lenticular Fotoform~ glass and glasses

I. Materials
A. Glass Ceramics
Since the last reporting period we have measured an additional 65
samples of glass-ceramic materials of which some 5 different samples
look promising. These samples are AU-3A, AU-4A, and AU-6A, and
particularly AS-4A and AS-9A. The first group, the AU series, have
particle concentrations somewhat greater than optimum making them less
efficient; however, the scattering appears to be nearly independent
of wavelength which is very desirable. Remelts of the AU series with
lower particle concentrations have been requested, as well as electron.
micrographs of AS-4 and AS-9. The remainder of the samples are not
suitable because of their specular transmission in the red.
.The optical data from all 65 samples are summarized in the data
appendix beginning with Tables Curves for T45 data vs.
axial gain are given in Figures A-1 and A-2 and the Gain (9) curves
along with tabular values of Gain (9) follow. It should be noted that
included with the compressed data is the brightness variation of each
sample within +45?, denoted by V45.
New samples of the same glasses AC-18 and AC-19 are designated AP and
AR, respectively. We have found that the AP and AR series are less
satisfactory than the AC-18 and AC-19 samples because there is considerable
specular transmission at the longer wavelengths. This seems to be
because of the smaller particle size. Electron micrographs of these
new samples are being prepared to establish this. Figure A-3 shows the
scattering particles in sample AC-19. The white bar represents 1 micron.
Clearly the average particle size is about .3 to .4 micron, exactly the
optimum size for the required uniformity.
As before most of the glass ceramics have predictable values of T45. In
every case where.a sample has a much less than optimum value of T45, Figures
A-1 and A-2, the particle concentration is too low and a large fraction of
the incident light is specularly transmitted. The high gains reported are
due to interference from the specularly transmitted light, and not due to
absorption or multiple scattering as with the commercial rear projection

screen materials. This stray light also has the effect of causing
the brightness variation to appear very large.
Several techniques of making thin layers of glass-ceramic material
are presently being investigated. Some of these techniques will be
used to make 12" x 12" prototype rear projection screens for
detailed visual evaluation.
B. Fotoform~ Glass
Investigations of the optical properties of this material are con-
tinuing; however, some time: delays have occurred because of diffi-
culties with an oven used for heat treating the glass. Three prototype
rear projection screens of this material measuring 3 inches square
have been fabricated. These are being ground and polished and will
be forwarded for further evaluation along with a data sheet of their
optical properties within the next two weeks.
The Ronchi ruling for making the lenticular samples has been made and
samples of this material will be fabricated as soon as repairs on the
oven are complete.
Work in this area is continuing; however, it has been quite difficult
to obtain sufficiently large metallic particles.
We are fabricating a mosiac to hold about 8 commercial rear projection
screen materials and 6 to 8 Corning Glass Works' materials. This will
be used for visually comparing different materials. It will be con-
structed so as to duplicate an actual projection system.
All electrical and mechanical parts of the modulation transfer function
analyzer are complete. Special sine-wave resolution targets are being made
and the complete system with the new masks will be available by the end of
December..
