Summary
This study introduces a method for calculating tunable-focus lens parameters and aberrations. Lens aberrations depend solely on fluid refractive indices, simplifying optical design.
Area of Science:
- Optics
- Optical Engineering
- Lens Design
Background:
- Tunable-focus lenses offer dynamic optical adjustment.
- Calculating third-order aberrations is crucial for lens performance.
- Existing methods may be complex for tunable systems.
Purpose of the Study:
- To develop a simplified approach for calculating paraxial parameters.
- To determine third-order aberration coefficients for thin refractive tunable-focus lenses.
- To identify key factors influencing lens aberrations.
Main Methods:
- Analytical approach to lens parameter calculation.
- Derivation of third-order aberration coefficients.
- Focus on fluid refractive indices as primary variables.
Main Results:
- A method for calculating basic paraxial parameters is presented.
- Third-order aberration coefficients are characterized by three functions.
- These functions depend only on the refractive indices of the lens-forming fluids.
Conclusions:
- The presented approach simplifies the analysis of tunable-focus lenses.
- Aberration coefficients are independent of object and pupil positions.
- This offers a more efficient design pathway for tunable optical systems.
