AS7265x − Typical Operating Characteristics
Optical Characteristics
All optical characteristics are optimized for diffused light. When
using a point light source or collimated light on the sensor, the
sensor opening must be covered by a lambertian diffuser with
achromatic characteristics. Diffusor of Tsujiden like D121UP
have been successfully tested at ams. If in the application
diffused light, e.g. used by a reflective surface, no additional
diffuser is required.
