| *1 Depending on factors such as the installation orientation and the vibrations of the environment, consider reinforcing the installation such as by implementing countermeasures to hold the lens in place. For information on the locations to hold the lens in place, see the installation examples. 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 the distance from the tip of the lens to the workpiece. Changing the magnification changes this distance. *3 The smallest resolvable feature able to be detected under 550 nm wavelength light. *4 The depth of field is a theoretical value calculated with an F-stop of 16 and a circle of least confusion of 40 µm. This varies depending on the F-stop. |
