... Integration time affects the measurement resolution. For better resolution, use a longer integration time. For short and fast conversions use a shorter integration time. The ISL29010 offers user flexibility in the integration time to balance resolution, speed and noise rejection. Integration time can be set internally or externally and can be programmed in the command register 00(hex) Bit 5 ...

... A thickness 1mm is recommended for a window lens design. The bigger the diameter of the window lens, the wider the viewing angle is of the ISL29010. Table 12 shows the recommended dimensions of the optical window to ensure both 35° and 45° viewing angle. These dimensions are based on a window lens thickness of 1 ...
