In simple words, Interferometry is nothing but the use of optical interference to carry out precise measurements of very small linear dimensions of slip gauges. The interferometer works on the same basic principle as that of an optical flat. In the previous article, we have discussed what is Interferometry in Metrology, in this article we […]
How to use Pitter–NPL Gauge Interferometer?
Interferometry is nothing but optical interference to carry out precise measurements of very small linear dimensions. Pitter–NPL Gauge Interferometer is one of the interferometers in metrology used for determining actual lengths of slip gauges. We will discuss this Pitter–NPL Gauge Interferometer construction and working principle with help of a schematic diagram in this article. As we mentioned above, […]
