Identifying Optical Materials with Precision Accuracy 04 Mar

Knight Optical

Precision accuracy is a critical necessity with any optical component. Rigorous testing to ensure strict compliance with given requirements will always be essential; it is a vitally important demand within any industry sector. Dimensional, surface profiling and optical performance testing are significant aspects of this process, but an additional layer of assurance and quality can be achieved with the use of material verification, employing methods such as refractive index, density testing and transmission measurement. This White Paper explores advanced techniques for precise optical material verification, overcoming the limitations of traditional testing methods.
