Iris Cryocooler Electronics (ICE)

Iris Technology Corporation

Breaking the paradigm of point-design solutions, Iris Technology developed a complete suite of "plug and play" cryocooler control electronics architected to support both traditional long-life space and tactical cryocoolers. Iris Cryocooler Electronics (ICE) support an incredibly wide range of technologies and power levels with applicability spanning from microsats all the way to deep space astronomy. These high efficiency, precision servo controllers are fully radiation hard, yet affordable for even the most cost-constrained missions. This qualified architecture has been scaled and successfully implemented into each product.
