          *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 the distance from the tip of the lens to the workpiece. Changing the magnification changes this distance.
          *3 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.
          *4 The pixel resolution is the field of view per pixel. This varies depending on the camera used.
          US = Unit cell size (size of 1 pixel)
          The CA-LMHR Series can also be used at pixel resolutions other than those listed here depending on the optical magnification.
          *5 The smallest resolvable feature able to be detected under 550 nm wavelength light.
