Adaptive Liquid Crystal Lenses - 20/20 Mag
The following is an excerpt from an abstract presented at the 2023 ARVO Annual Meeting. “This study compared the power diopter obtained from liquid crystal lenses as measured by mechanical (manual) lensometer measurements. The liquid crystal lenses exhibit similar diopter power to one another at each of the settings between 0.00 to 2.50 D.

Liquid Crystal Lens Filters out Light that Causes Seizures
3 天之前 · The lens exhibited tunability of temperature variation, showing its potential as an adaptable, responsive means to filter damaging light. “This is a hugely exciting project that . . . demonstrates the potential for the use of liquid crystal lenses that can be modulated to cut out specific wavelengths of light,” Ahmed said.
LIQUID CRYSTAL LENSES: Liquid crystals ... - Laser Focus World
2010年12月22日 · Liquid-crystal materials and LC lenses. Liquid crystals are mesophases between crystalline solids and isotropic liquids, typically consisting of elongated, rod-like organic molecules with a size of a few nanometers. These molecules contain both the rigid and flexible parts of the crystal.
Liquid crystal lenses with tunable focal length: Liquid ...
2018年3月1日 · Lenses with tunable focal length play important roles in nature by helping species avoid predators and capture prey. Many practical devices mimic lens concept for imaging, sensing, and detection. This review covers fundamental optics of lenses and its extension to lenses made of liquid crystals (LCs).
