Area of Science:

• Optical Engineering
• Computational Optics

Background:

• Traditional optical system design relies heavily on designer experience, leading to inefficiencies.
• Developing athermal and achromatic optical systems presents significant design challenges.

Purpose of the Study:

• To propose a novel method for constructing initial structures of athermal and achromatic optical systems.
• To automate the selection of lens materials and optimization of structural parameters using particle swarm optimization (PSO).

Main Methods:

• Implementation of a particle swarm optimization (PSO) algorithm for optical system design.
• Automatic selection of optical materials and optimization of structural parameters.
• Design and validation of an optical system within a specific wavelength range (450-750 nm).

Main Results:

• The developed PSO method successfully designed an athermal and achromatic optical system.
• The system demonstrated high performance with Modulation Transfer Function (MTF) values exceeding 0.42 at 45 lp/mm.
• The system maintained consistent MTF performance across a wide temperature range (-50°C to +70°C).

Conclusions:

• The proposed PSO-based method significantly enhances the efficiency of designing athermal and achromatic optical systems.
• The method provides a robust approach for achieving high-performance optical systems that are stable across varying temperatures.
• This automated design strategy meets demanding application requirements for optical systems.
