Gauthier Collienne Posted November 17, 2023 Report Posted November 17, 2023 Hi, According to the ISO-8980-1/2 standard (Ophthalmic optics — Uncut finished spectacle lenses), both principal power meridians must be controlled at the primary reference point. Because the DCS is used worldwide in the ophalimic industry, I would like to propose to add the tags S1 and S2 in the DCS document. As there are measurable values, it makes sens to create these tags with the LD*, TOLV*, INS*, TOL* and CK* tags. So, for the lower principal power meridian, we have: S1 => prescribed value LDS1 =>designed value TOLVS1 =>tolerance values INSS1 =>inspected value TOLS1 => result of the tolerance test CKS1=>activation of the control And fo the highest principal power meridian, we have S2 => prescribed value LDS2 =>designed value TOLVS2 =>tolerance values INSS2 =>inspected value TOLS2 => result of the tolerance test CKS2=>activation of the control note : This topics was discussed shortly during the last DCS meeting in september 2023.
