Design of a multilevel diffractive lens (MDL, MDL-100B) with diameter = 100 mm and focal length of 200 mm. This MDL has a ...

Diffractive lenses are not perfect but work. Twelve years ago at the AECOS meeting, a program chair asked the audience if in 10 years we would be able to achieve near vision for our cataract ...

A diffractive lens bends light using etchings and patterns on its surface. Daniel Apai/University of Arizona, CC BY-ND. Because it is the surface texture of the lens that does the focusing, ...

The flat lens, which is technically referred to as a multi-level diffractive lens (MDL), is 100 millimeters in diameter and offers a 200mm native focal length.

Engineers have developed a new type of thin, flat, and ultralight lens which can still bend light to a single point like traditional lenses. The development could see future cameras use paper-thin ...

However, the Utah team's multilevel diffractive lens (MDL) is able to bring all the wavelengths of light for which it was designed to detect (400–800 nanometers, ...

The durability of the diffractive beam combiner far exceeds the two-lens system alternative. Also, the integral light transmittance of the diffractive dual wavelength element outperforms any on-axis ...

SAN FRANCISCO — Multifocal diffractive lenses can be used with confidence in patients who have previously undergone laser vision correction, according to a speaker at the American Academy of ...

The diffractive achromat from Holo/OR offers diffraction limited performance due to the absence of aberrations, while maintaining high laser damage threshold and low thermal sensitivity. Performance ...

Thin, simple diffractive lenses are notorious for their blurry images, so they have never been used in astronomical observatories. But if you could improve their clarity, ...
