*1 The above values were calculated according to optical design values. Actual values for individual lenses will differ according to precision of assembly.
*2 WD indicates a working distance at reference magnification. WD will vary depending on magnification adjustment.
*3 Depth-of-field applies to an F-stop of 16. Depth-of-field varies depending on F-stop setting.
The indicated depth-of-field is a theoretical value that assumes 1/2" image sensor size and a horizontal resolution of 320 lines. (Circle of least confusion is 40 µm 1.57 Mil in the image)
*4 The smallest resolvable feature able to be detected under 550 nm wavelength light.
