^1 The above values are all calculated according to optical design values. Actual values for individual lenses will differ according to precision of assembly. ^2 Working distance indicates a working distance of each lens at reference magnification. Working distance will vary depending on magnification adjustment. (Excluding CA-LM1/LMA1) ^3 The indicated depth of field is a theoretical value that assumes 1/2" or 2/3" Image/CCD size and a horizontal resolution of 320 TV 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.
