量块是长度计量中地位最重要、应用最广泛的基本量具 ,大部分长度量具的量值均需通过量块溯源到长度基准。柯氏干涉仪是一种传统的精密光学测量仪器 ,它以氪灯波长作为测量基准 ,可用于二等标准量块 (测量不确定度 0 .0 5 + 0 .5Ｌμｍ ,Ｌ为被测长度 ,单位ｍｍ )的测量检定 (
Measuring block is the most important position in the length measurement, the most widely used basic measuring tools, most of the length of the gauge need to go through the length of the amount of mass reference. Korotkoff interferometer is a traditional precision optical measuring instrument, which krypton lamp wavelength as a measurement basis, can be used for second-class standard measuring block (measurement uncertainty 0. 05 +0 .5 Lμm, L is the measured length, Unit mm) measurement test (
