The following figure shows the area in which the image can be moved and the guaranteed optical performance
range of this product.
The center of the crosshair is the optical axis of the lens.
The octagonal area excluding the four corners (light gray) is the guaranteed optical performance range. Note
that the sizes of the four corners that are outside the guaranteed range are the same.
※
Moving the image outside the guaranteed optical performance range may cause shade to appear in the corner area of the
image. (e.g., 60% vertical, 10% horizontal
→
the upper right corner of the image becomes dark)
We recommend that you do not use the product in this manner but rather adjust the installation position so that the image
is within the guaranteed range.
