  1. Calculated at minimum object distance.
  2. Working distance: distance between the front end of the mechanics and the object.
  3. High transmittance across the wavelength range due to broadband AR coating. Designed for imaging with single wavelength narrowband illumination.
  4. Percent deviation of the real image compared to an ideal, undistorted image.
  5. Measured from the front end of the mechanics to the camera flange at infinity focus.
