OPT3004DNPR

The strong IR rejection feature in the OPT3004 sensor is important because many real-world lighting sources have significant infrared content that humans do not see. If the sensor measures infrared light that the human eye does not see, then a true human experience is not accurately represented. Additionally, if the ambient light sensor is hidden underneath a dark window where the end-product user cannot see the sensor, the infrared rejection of the OPT3004 becomes significantly more important. This is because dark windows attenuate visible light but transmit infrared light, amplifying the ratio of infrared light to visible light that illuminates the sensor. The high infrared rejection of the OPT3004 ensures that results can still be well matched to the human eye under these conditions.

The operating temperature range of the OPT3004 Ambient Light Sensor is -40°C to +85°C.

The spectral response of the OPT3004 sensor closely matches that of the human eye, including significant infrared rejection over a wide angle of incidence. This is important for creating a good human experience and ensuring that optical conditions are optimal for humans. The device's strong IR rejection ensures that the sensor accurately measures the same spectrum of light that the human eye sees, even in situations where the sensor is hidden under dark glass. The OPT3004 is designed to accurately meter the intensity of light as seen by the human eye, making it an ideal replacement for other ambient light sensors with less human eye matching and IR rejection.
