The designation gives the clear internal diameter and ring thickness in tenths of a millimetre. For example, 36-10 means a 3.6 mm opening and 1.0 mm ring thickness. The example 36-10 is not among the verified selectable variants.

The outer ring has a 17 mm outside diameter and 1.6 mm ring thickness. The centred lower post is 1.0 mm wide. Side mounts are not shown.

The proportions are geometrically correct. The image is enlarged on screen. Lighting presets are simplified illustrations, not calibrated reproductions of real lighting, fog or visual acuity. The geometric clearance is expressed at the aperture plane. The 50 m distance is measured from the eye to the target.
