1. The space enclosed by the MTF curve, the
horizontal axis and the vertical axis, the larger the area, the better, and the
better the lens imaging performance. The flatter the MTF curve, the better. The
flatness indicates the imaging uniformity of the edge and center of the lens.
2. The closer the sagittal curve and the
meridian curve, the better, and the more consistent the imaging in different
directions.
3. The low frequency curve represents the
contrast characteristics of the lens, and the high frequency curve represents
the resolution characteristics of the lens.
