*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/CCD size and a horizontal resolution of 320 lines. (Circle of least confusion is 40 µm in the image) *4 The smallest resolvable feature able to be detected under 550 nm wavelength light.
