IR Optics: Efficient Testing Throughout the Manufacturing Process

Presented by:
  • Patrik Langehanenberg, Trioptics
  • Christian Domagalski, Trioptics

In the manufacturing process of IR optical systems — for security and defense applications, for example — the nontransparency of the lens materials in the visible spectral range (VIS) leads to special requirements on the assembly and test equipment.

Whereas the assembly process in many cases can be accomplished by using cost-effective VIS equipment, other testing steps require a test bench specifically designed for IR. This is particularly true for the final inspection and when the root cause for out-of-spec assemblies needs to be identified. Here, a solution for the full optomechanical characterization in the infrared is required.

Patrik Langehanenberg, Ph.D., and Christian Domagalski present solutions regarding how to make the manufacturing process of IR objective lenses more efficient by using adequate techniques for centration-based alignment testing, IR modulation transfer function (MTF) analysis, and noncontact determination of center thicknesses and air spacings.
