Table 1: Recommended dimension for optical window
( All dimensions are in mm )
Note : Active area center to coincide with window
center (flat or with light guide).
The window should be placed directly on top of the
photo sensor to achieve better performance and if a
flat window with a light pipe is used, dimension D2
should be 1.5mm to optimize the performance of
APDS-9004.
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.
