Window and Light Guide Recommendations
Transparent window with IR coating (IR pass of around 90% and minimum 30% visible pass) is recommended in order to
pass both visible and infrared light. 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 below.
Recommended Plastic Materials
* Transmittance of visible light will reduce if plastic window is coated with IR ink
To ensure that the performance of the APDS-9800 will not be affected by improper window design, there are some
constraints on the dimensions and design of the window so that the maximum size of the window, which is placed in
front of the photo light sensor, will not affect the angular response of the APDS-9800. This maximum dimension that is
recommended will ensure an acceptable light reception cone.
The distance between the bottom of the window and the sensor top–the air gap– should be as close as possible and not
more than 0.2 mm. For optimum performance, windows thickness should be limited to not more than 0.8mm.
