Abstract

This paper presents an optimization-based approach for the first-order design of infrared triplet systems in the LWIR spectral range. The method is based on paraxial optical theory and formulates the design task as a multi-parameter optimization problem aimed at minimizing chromatic aberrations and Petzval curvature under given constraints. Numerical optimization techniques are applied to determine the optical powers and spacing between the lenses. The obtained results demonstrate stable and physically realizable first-order solutions, validated through convergence of the iterative optimization procedure. The proposed framework provides an efficient and extensible approach for preliminary infrared optical system design.
