2.1 Optical Window Material
The material of the window is
recommended to be polycarbonate.
The surface finish of the plastic
should be smooth, without any
texture.
The recommended plastic material
for use as a window is available
from Bayer AG and Bayer Antwerp
N. V. (Europe), Bayer Corp. (USA)
and Bayer Polymers Co., Ltd.
(Thailand), as shown in Table 2.
