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

Table

4-1 on page 4-1

). Powering VCC_ILLUM off of 3.3 V yields slightly improved

working ranges in darkness.
