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.
