标准范围

本文件规定了用于测量眼镜镜片的焦距计的校准和验证的参考镜片的要求，例如那些符合ISO？8598-1.它还给出了确定参考透镜后顶点光焦度的方法。笔记？公认的是，也可以使用具有给定范围内的光焦度的其他参考透镜，按照相同的精度和形状标准制造，但具有不同的后顶点光焦度。然而，只有具有整数标称焦度的透镜，如4.1所述，可用于校准数字舍入焦距计。

This document specifies requirements for reference lenses for the calibration and verification of focimeters that are used for the measurement of spectacle form lenses, e.g. those complying with ISO 8598-1. It also gives a method for the determination of the back vertex power of the reference lenses.

NOTE            It is accepted that other reference lenses can also be used with powers within the given range, manufactured to the same standard of accuracy and form, but different back vertex powers. However, only lenses with integer nominal powers, as described in 4.1, can be used for the calibration of digitally-rounding focimeters.
