designed. The lens consists of 3 plastic aspheric lenses, one glass spheric lens and an infrared glass filter. CMOS
OV16850 with a pixel size of 1.12 micrometers
from Omni Vision is used as an image sensor. The lens has an effective focal length
of 4.483 mm, a F-number of 2.50, a field-of-view
(FOV) of 76.2 degree, and a total length of 5.873 mm. The maximum distortion
of the lens is less than 2.0%. The minimum value of all field relative illumination
is over 39.8%.
