NOTES :

1. Image area : 3.67 mm (H) x 2.76 mm (V)

2. TV distortion is defined by the formula, (∆y/y) x 100 [%]

at capturing rectangular pattern sized horizontal by

vertical as 4 by 3.

"y" is defined as the vertical height of center of the

horizontal line.

"y" is defined as the difference between the vertical

height of the center of the horizontal line and edge of it.

3. The best focus point of an object can be obtained by

Y turning the lens head within this range.

4. Torques which are necessary for turning the lens.
