Abstract:

Traditional varifocal metalenses are limited by their bulky dimensions and tuning complexity, suffering from inherent chromatic aberration that significantly reduces broadband applicability. In this Letter, a single-layer achromatic metalens with polarization-dependent focal length is proposed. An achromatic focusing over a range of 10-11.5 μm is achieved by interference of multi-atomic units with stable intensity superimposition. The focal length could be tuned from 0.93 to 1.05 mm with a low coefficient variation of <1.75% by simply adjusting the polarization of incident light. Our work opens new possibilities for portable imaging devices in the future.

Focusing of Light in the Eye

Focusing of Light in the Eye

Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
