Engineers at Research Frontiers Inc. in Woodbury, N.Y., have developed a faster process for making light-controllable film by curing it with ultraviolet radiation rather than heat.
The process enables manufacturers to produce electrically controllable films whose light transmission can be varied rapidly by the user. These films feature the company's suspended particle device technology, providing control over the amount of light transmitted through windows, sun roofs, sun visors and eyewear.
