Research Frontiers Inc. is a technology company that develops and licenses its patented Suspended Particle Device (SPD) light-control technology. Marketed as SPD-SmartGlass, this technology enables glass and plastic surfaces to instantly and precisely switch from clear to a user-controlled level of tint. The system operates via a film containing microscopic particles that align when an electrical voltage is applied, regulating the passage of light. Key features include rapid transition speed, variable tint control, and the ability to block over 99% of UV radiation and significant heat, enhancing energy efficiency. The company licenses its technology to a global network of partners for use in products across the automotive, aviation, marine, rail, and architectural industries.
