It is not difficult to imaging, that the optomechanical design has a large impact on the overall HDR performance as well. Should the application require a consistent performance over a wider wavelength range, as it does for a dual-band (e.g., VIS + 940nm) application, or even across the entire VIS to NIR band in hyperspectral applications, fundamental design decision can have an increased impact. Optimizing just 1 image path, while suppressing hundreds or even thousands of others is not trivial and requires a deep design and manufacturing process experience.

Designing and manufacturing an HDR lens is probably as much art as it is science and engineering. New imagers can capture light intensity variations up to six or more orders of magnitude within the same image frame (+120db HDR, 20*LOG(1e6)), and together with the growing number of applications using computer vision, they are putting very demanding requirements on lens performance.
