OPT3001: The issue of glass transmittance on the window of the shel

The application scenario is to detect environmental changes and provide early warning (usually installed in a fixed dark area), which means that this product should be in closed dark conditions for a long time, and there may be environmental changes (such as turning on the lights, external lighting after opening the door, etc.). After the device is moved and the light changes, the high transmittance of the warning may directly see the circuit board inside the product, which is not very beautiful


What is the recommended glass transmittance for the window on the shell when using OPT3001? Please help confirm, thank you!
