title: Measurement techniques used in the optics workshop.
abstract: Measurement techniques used in the optics workshop often are complex and demanding. Characteristics considered are flatness, parallelism, angularity, curvature, length, and surface quality. Types of measuring equipment common to the workshop and their relative accuracies are discussed. The present usage of the Kösters prism as a workshop measuring device is also discussed.
