Notes:
1. Near distances are FOV limited.
2. Contrast is measured as Mean Reflective Difference (MRD) at 670 nm.
3. Working range specifications at temperature = 23°C, pitch=15°, roll=0°,
skew=0°, photographic quality, humidity 45-70%RH.
4. Range measurements are when VCC_ILLUM is powered off of 3.0 V (see
4-1 on page
4-1). Powering VCC_ILLUM off of 3.3 V yields slightly improved
working ranges in darkness.
