Overall BTC Technologies

Photonics

Photonics is a critical core technology to nearly all of what BTC does. BTC’s ability to sort, manipulate and rapidly identify specific wavelengths and then associate them with elements, materials, liquids, etc., is a primary capability. It is the interplay between photonics and acoustics that lies at the heart of our acousto-optic tunable filter technology. We develop electro-optic and magneto-optic devices, subsystems and systems to review elements, materials, colloids, etc. BTC has a fully stocked photonics lab that features modulators, fast switches, frequency shifters, wavelength selection, laser scanning and other means to satisfy customer requirements.

Field Assisted Sintering Technology (FAST)

Brimrose is working with Dr. Jogender Singh at Penn State University to use extremely high pressure to make next-generation compounds. We have already received contracts from NASA-Langley for radiation shielding and the Missile Defense Agency for mirrors. We are also working on the next-generation of body armor to protect soldiers in the field.

The FAST process is made possible by large presses (see accompanying diagram)  manufactured in Germany by FCT Systeme that can provide hundreds of tons of pressure on metals. These presses, several of which are deployed by our partner, Dr. Singh at Penn State, are defining a new generation of metallurgy that have the potential to revolutionize jet engine parts, mirrors, shielding, cutting tools, hypersonic vehicle parts, sensors-MEMs, thermo-electric materials and thermal management microelectronics.
