8.2.2.1 Optomechanical Design

After completing the electrical design, the next task is the optomechanical design. Design a product case that includes a window to transmit the light from outside the product to the sensor, as shown in Figure 8-2. Design the window width and window height to give a ±45° field of view. A rigorous design of the field of view takes into account the location of the sensor area, as shown in Section 11. The OPT3001-Q1 active sensor area is centered along one axis of the package top view, but has a minor offset on the other axis of the top view. Window sizing and placement is discussed in more rigorous detail in the OPT3001: Ambient Light Sensor Application Guide application note.
