Lightweight, miniaturized optical imaging systems are vastly anticipated in these fields of
aerospace exploration, industrial vision, consumer electronics, and medical imaging …

Wide field-of-view (FOV) optics are essential components in many optical systems, with
applications spanning imaging, display, sensing, and beam steering. Conventional …

In this paper, the material removal characteristics and mechanism of submerged pulsating
air jet polishing (SPAJP) process are investigated by polishing experiment on K9 glass and …

A lens performs an approximately one-to-one map** from the object to the image plane.
This map** in the image plane is maintained within a depth of field (or referred to as depth …

Metasurfaces are planarized and miniaturized versions of conventional optical elements.
Subwavelength‐thick single‐layer metalenses have diffraction limited resolution for on‐axis …

It is generally assumed that correcting chromatic aberrations in imaging requires multiple
optical elements. Here, we show that by allowing the phase in the image plane to be a free …

Optics in the mid-wave-infra-red (MWIR) band are generally heavy, thick and expensive.
Here, we demonstrate multi-level diffractive lenses; one designed using inverse design and …

Diffractive lenses can be very thin and light. They usually suffer from chromatic aberration
and work only over a narrow range of wavelengths but so-called achromatic diffractive …

Diffractive optical elements are becoming increasingly popular due to their ability to provide
a broad spectrum of design possibilities by manipulating Fresnel regions. These design …

Diffractive optical elements are increasingly favoured due to their ability to provide
numerous design freedoms by adjusting the Fresnel regions. The design freedoms make it …
