Abstract
A description is given of the ILK-25 interference-type linear comparator. The metrological characteristics are given element by element for a long-range phase-type linear displacement meter, the IPL-FD. The instrumental error of the IPL-FD in an appropriate method of measurement is not more than 0.05 mm. It is concluded that the IPL-FD can be used in a length standard for long-range measurements.
