    Area of Science:

    • Optical Metrology
    • Interferometry
    • Lens Characterization

    Background:

    • Accurate measurement of lens refractive index is crucial for optical system design and performance.
    • Traditional methods can be complex, time-consuming, or limited in applicability to specific lens types.

    Purpose of the Study:

    • To present a novel, non-immersive method for measuring the refractive index of lenses.
    • To simplify the measurement process by focusing on back surface refraction.
    • To achieve high accuracy in refractive index determination, applicable to both spherical and aspherical lenses.

    Main Methods:

    • Utilizes fiber point-diffraction longitudinal interferometry.
    • Simplifies the lens imaging model to single refraction at the back surface.
    • Measures lens thickness, back surface radius of curvature, and object-image point distance.

    Main Results:

    • Experimental validation demonstrates an accuracy better than 2.2 × 10⁻⁴ for refractive index measurement.
    • The method effectively excludes the front surface from the imaging process.
    • Successfully measured the refractive index of aspherical lenses.

    Conclusions:

    • The proposed fiber point-diffraction longitudinal interferometry method offers a simple and accurate approach to lens refractive index measurement.
    • Its ability to exclude the front surface makes it versatile for measuring complex lens geometries, including aspherical surfaces.
    • This technique provides a valuable tool for optical metrology and lens manufacturing.
