Abstract
A system for control of optical properties of light comprises a cell comprising a first optically transparent member and a second optically transparent member. The members are disposed in a vertical direction, parallel to each other and at a distance from each other with closed edges, thereby defining a space therebetween. A first fluid is configured to be received within the space. A second fluid, different from the first fluid, is configured to be received into the space, while at least a portion of the first fluid is disposed in the space, causing the first fluid to be displaced. The first and second fluid interface with each other, while remaining separate. The second fluid is configured to be withdrawn from the space leaving the first fluid in the space.
