Evaluation of the uncertainty for the measurement of a gauge block by optical interferometry is presented. The measurement method which serves as the basis for the uncertainty evaluation is consistent with popular measurement techniques which apply t

A laser diffractometer for calibrating grating pitch is being developed at the National Research Council (NRC). Based on the METAS design, it features a precision rotary table, the sample grating mounted in Littrow configuration, a collimated spatial

This work describes the development of a grating diffratometer to provide traceable calibration of grating pitch in range 20 μm to 350 nm. The approach is based on the Littrow configuration in which a laser beam is directed onto the grating which is

A long gauge in the form of a thick-walled tube is converted to a Fabry-Perot cavity by attaching partial reflectors to its ends. The length of this gauge is determined from a number of absolute frequency measurements of the cavity resonances. A set
