PHILLIPS 202 ACE DIDYMIUM FRAME
SELECTION
Schott Glass Technologies has developed a new
contrast enhancement glass for spectacle lenses.
The new material, called Phillips 202 ACE, short for
"Amethyst Contrast Enhancer," utilizes rare
earth oxides in the glass composition to achieve
the unique color enhancing characteristics.
Basically, the color enhancement concept works
by selectively positioning transmission in the
blue, green, and red spectral regions whereby
one can improve the color discrimination between
different color objects. These are the same
colors used to produce a color television
picture. They optimize the readability of such
displays under high ambient light conditions.
Phillips 202
ACE Glass utilizes rare earth oxides in its
composition to provide the same filtration. This
glass is very efficient in filtering sodium
flare in addition to providing ultraviolet
protection to 390 mm. The Phillips 202 ACE glass is
becoming a preferable choice of lamp workers. It
is very comfortable for viewing under high
ambient light conditions such as when working
with glowing heat sources for a duration of
time. Also, although it has a relatively low
luminous transmission of 38%, it is not
recommended for sun protection use unless UV
filtering coatings are applied.
