Paper Abstract

Instruments incorporating low power He-Ne lasers are used in construction and agriculture for rapid and accurate leveling and alignment. The optical systems used in these instruments must meet extremely high accuracy requirements yet be low cost and function reliably in a rugged environment. This paper is a case study of the optical design used in one of these instruments. The overall operation of the instrument is presented with emphasis on accuracy and environmental requirements. The general design criteria for the optical system are reviewed and the major components described. Using a recently developed product as an example, a detailed design of the optical system is developed. The various design alternatives that were considered during development to achieve high performance, low cost and efficient manufacturing are discussed.
