Cryogenic Optical Refrigeration

CryoRayTM cooling technology was invented by Richard Epstein and his team at Los Alamos National Laboratory (LANL).  Over the past two decades Dr. Epstein together with Prof. Mansoor Sheik-Bahae’s group at the University of New Mexico (UNM) and others has improved and refined this technology.  In 2009, Dr. Epstein cofounded ThermoDynamic Films, LLC (TDF), to commercialize CryoRay coolers and other energy-related technologies.

CryoRay coolers are the technology of choice for applications that require cryogenic cooling with zero vibration, high reliability and low mass (See Applications).  These applications include space-borne infrared imaging, unattended surveillance cameras, gamma-ray spectrometers that use cooled germanium crystals, high-precision laser-based metrology, compact conventional electronics and high-temperature superconducting electronics and others. 

Much of the support for the development of CryoRayTM coolers has come from government funding through the Air Force, DARPA, NASA and the DOE.  TDF is teaming with scientists at universities, national laboratories and industry to deploy CryoRay coolers for sensor, metrology and electronics applications.  TDF is interested in teaming with other entities to help solve their cryocooling needs.
