Astronomical imaging camera lens for 0.35-0.9 mum with variable chromatic correction

Area of Science:

• Optical engineering
• Astronomy

Background:

• Chromatic and spherochromatic aberrations limit astronomical imaging quality.
• Achieving variable correction across multiple astronomical bands (U, B, V, R) is challenging.

Purpose of the Study:

• To design an imaging lens with zoom-like variable chromatic and spherochromatic correction.
• To achieve high-fidelity astronomical imagery in the U, B, V, and R bands.

Main Methods:

• Lens design at f/4 aperture.
• Incorporation of zoom-like correction mechanisms.
• Analysis of performance across U, B, V, and R spectral bands.

Main Results:

• The designed f/4 lens exhibits variable chromatic correction.
• The lens demonstrates variable spherochromatic correction.
• Correction is effective for astronomical imagery in the U, B, V, and R bands.

Conclusions:

• The f/4 imaging lens successfully integrates zoom-like variable chromatic and spherochromatic correction.
• This design advances the capability for high-quality astronomical observations across key spectral bands.
