IRflex Signed SBIR Phase II Contract for Optical Additive Manufacturing in Mid-Wave and Long-Wave Infrared Bands

On May 10, 2024, IRflex Corporation signed a SBIR Phase II contract of $981,450 of with NAVAIR  for Optical Additive Manufacturing in Mid-Wave and long-Wave Infrared Bands after successfully finish its Phase I contract since May 2023.

The military extensively uses mid-wave infrared (MWIR) and long-wave infrared (LWIR) sensors and cameras for reconnaissance and surveillance of targets of interest by thermal emissions. IR cameras require broadband imaging systems composed of several IR lenses made of different materials to correct for chromatic aberrations (focal shift caused by dn/d-wavelength) or for a thermalization (focal shift caused by dn/dT). IR cameras and the high-definition imaging systems are very expensive and are often exposed to harsh environments (sand, salt water, vibration, temperature variation, etc.) and can be damaged. The potential use of MWIR-LWIR AM to print imaging quality optical lens is highly desirable and critical for current and future Navy IR optical systems. The AM process has the potential for depositing MWIR and LWIR optical precursor materials with sufficient quality and precision for IR optical components or to perform front surface repair on existing IR optical components. The MWIR-LWIR AM will allow engineering of new compact optical systems with high imaging performance, fewer optical elements, less weight and volume, and easier alignment compared to current multi-components IR imaging optics.

The Phase II contract starts from August 1, 2024 and finish until February 1, 2027.
