OPT3001: OPT3001 Calibration certificate ?

Hello,

Thank you for posting to the Sensing forum.

We do not offer a calibration certificate for the OPT3001, but it is calibrated to +/- 10%, and if no glass is placed over the sensor then no additional calibration is needed. If glass or a cover is placed over the sensor then the transmission of the glass should be checked. As transmission decreases error will increase and calibration may be needed.

and here for details if a glass is placed on top of sensor: https://e2e.ti.com/support/sensors/f/1023/t/884142
