ISO 1011012 specifies rules for the presentation of aspheric surfaces and surfaces with low order symmetry such as cylinders and toroids in the ISO 10110 series, which standardizes drawing indications for optical elements and systems. It also specifies sign conventions and coordinate systems. Note 1: For off axis aspheric and non symmetric surfaces, see ISO 10110 19. ISO 1011012 does not
