For 25 mm Spectacle Lens - without adapter
Your individual, improved spectacle lens is put in the ahg-monoframe.
With the help of a set adapter and a clamp, the ahg-monoframe is mounted centrally in front of the sight disc or the iris disc. Therefore, your sight defect is corrected directly on the iris disc, consequently aiming mistakes are avoided to a large extend.
Only spectacle lenses with an outer diameter of 24 mm can be used.
ahg-monoframe corresponds to ISSF Rules from 1.1.17
