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=18°, roll=0°, skew=0°, photographic quality, ambient
light ~30 ft-c, humidity 45-70%RH.
4. Distances measured from front edge of scan engine chassis.
