What is Understanding Liquid Lens Technology about?

A liquid lens uses fluids instead of mechanical parts to create a variable focus lens. There are two main types - transmissive lenses use two immiscible fluids of different refractive indices, while reflective lenses spin mercury to create a smooth reflective surface like a mirror (used in large telescopes). Transmissive lenses can change focus rapidly through electrowetting and are used in applications like endoscopes and cameras. Reflective liquid mirror telescopes are much cheaper than solid glass mirror
