Abstract

The fabrication of aspheric elements by means of replication has become a very important method of supplying otherwise difficult to produce components. The Schmidt Corrector Plate is a typical example, the major benefit being projection TV for the consumer market. However, prior to this it is necessary to develop an objective test method. This paper describes a laser ray trace method of measuring the aspheric profile to ±5 il and subsequently using the derived coefficients to calculate the system M.T.F.' Using this as the quality criteria an objective test method has evolved. The systems shortcomings are discussed, and it is concluded that a useful production test method has been developed.
