Diffractive-refractive hybrid corrector for achro- and apochromatic corrections of optical systems

Area of Science:

• Optics
• Optical Engineering
• Lens Design

Background:

• Chromatic aberration is a common issue in optical systems, limiting image quality.
• Achieving full chromatic correction (apochromatic) is challenging, especially with residual aberrations.

Purpose of the Study:

• To demonstrate the feasibility of correcting any residual chromatism in optical systems.
• To introduce a novel diffractive-refractive hybrid corrector for chromatic aberration correction.

Main Methods:

• Designing and analyzing optical systems incorporating a hybrid corrector.
• The corrector consists of one diffractive lens and one or two refractive lenses.
• Evaluating the system's performance across different wavelengths to assess chromatic correction.

Main Results:

• The proposed hybrid corrector effectively achieves achro- and apochromatic correction.
• The method is applicable to optical systems with any level of residual chromatism.
• Successful correction was demonstrated using a combination of diffractive and refractive elements.

Conclusions:

• A diffractive-refractive hybrid corrector offers a viable solution for advanced chromatic aberration correction.
• This approach enables the design of high-performance optical systems with superior color fidelity.
• The findings open new avenues for optical system design and aberration management.
