Abstract

Achieving precise tolerances in the assembly of optical components is crucial for the performance of off-axis optical systems. This study focuses on the design and evaluation of assembly methods and mechanisms of an Offner spectrometer with the goal of demonstrating their capability to achieve tolerances within 40 microns. The methodology involves the development of assembly methods and mechanisms specifically tailored for off-axis optical systems. Representative models of optical components and custom adaptors were designed and manufactured to facilitate the assembly process. Procedures were devised for setting up, repositioning, and locking the representative models. The proposed methods and mechanisms were evaluated using measurements from a Coordinate Measuring Machine (CMM). The accumulated tolerance in each step of the assembly process was analyzed, ensuring that the overall performance met the desired specifications. The findings validate the effectiveness and reliability of the developed approach, offering valuable insights for the design and implementation of similar systems.
