Gravity compensated liquid lens EL-16-40-GTC

Liquid lenses have become a reliable solution for fast, compact, reliable and repeatable focusing in imaging but also laser applications, and with the new gravity compensation technology it is now possible to achieve outstanding optical performance also for large clear aperture lenses when they are used in a horizontal optical axis. By adding a second layer of optical liquid with different density and a second optical membrane it is possible to passively compensate the gravity-induced coma of single liquid lenses to a negligible value well below 0.05 lambda RMS for any lens orientation and without sacrificing any other performance parameters.
