In my search for high quality optics to do close-up photography with my superzoom digicam, I came across several web pages that list good achromatic lenses. These are filter mount lenses, sometimes called "doublet" or "2 element" lens or "close-up filter". On this page I'll combine ...

A hydrogel contact lens made up of a material that imitates the chemistry of natural cell membranes to minimize changes in ocular physiology. l. blank A moulded piece of ophthalmic glass before completion of the surfacing processes. See glass; lens, semi-finished. l. capsule See capsule; lens...
The image quality and the resolution were close to the ones recorded by the commercial objective lens with the similar NA (Fig. 5f). Thus, the demonstrated achromatic TiO2 metalens can perform on par with the commercial products for optical imaging. Considering its compactness, flatform, high-...

We have demonstrated the compensation of the chromatic dispersion of a fiber-integrated lens via 3D-nanoprinted meta-optics, opening up the possibility to create a large modulation range of the TBP and the group delay. Fixing the in-plane rotation angles of nanopillar meta-atoms to 0 and 90 ...
Large 70mm objective lens: Our refractor telescope is equipped with a large 70mm aperture objective lens that provides enhanced, brighter views compared to the 50mm model while adding very little additional weight. Setting up and using the Travel Scope is quick and easy. ...

As the most basic and important functional element, converging lens plays a crucial role in various optical systems. The typical distribution of phase retardation for a metalens follows: $$\varphi \left( {R,\lambda } \right) = - \left[ {2{\rm{\pi }}\left( {\sqrt {{R^2}{\rm{ +...
we can achieve a group delay range of about 5 femto-second in our 600-nm-tall TiO2nanofins. There are some possible ways to circumvent this limitation, e.g. through hybrid diffractive-refractive lens design38,39, high-aspect ratio nanofabrication to increase structure height40,41and using hype...
