The JIS B 0090 family of standards specifies the representation of design and functional requirements for optical elements and systems in drawings used for manufacturing and inspection. This standard specifies conventions for indicating eccentricity tolerances for optical elements, subassemblies, and assemblies. These conventions apply only to rotationally symmetric optical systems. Note: The corresponding international standards for this standard are shown below. The symbols representing the degree of correspondence are IDT (matched), MOD (modified), and NEQ (not equivalent) based on ISO/IEC Guide 21.
