The requirement involved an optical system comprising filters and prisms, and presented the following challenges:
- The optical components needed to be manufactured to a tight tolerance, with durability a key performance requirement
- The lens rejection rate also pushed up the build cost.
Working from the existing optical set up and application, we developed a turnkey solution that essentially combined the various optical components into one unit. The result was a more durable system, a more reliable production process, less polished surfaces and AR coatings, and ultimately a dramatic reduction in the build cost.
