Excelitas precision spherical lenses can be customized in lens size and radius curvature to serve your specific application best. Our infrared spherical lenses are specially designed to meet the needs of demanding military applications throughout the infrared. Using our advanced plasma source (APS) coating technology, these spherical lenses offer superior resistance to environmentally-induced damage degradation and enable precise control over part distortion on high aspect ratio parts.
Our infrared spherical lenses include high-performance FLIR imagers that incorporate laser lines and other IR laser-based systems, such as those used in laser targeting and IR countermeasure applications. These spherical lenses are fabricated from a variety of substrate materials and provide operation over the 3 µm to 14 µm spectral range. Component diameters are available from 6 mm to 250 mm, and the typical surface flatness for these optics is λ/10 (at 633 nm). In addition, our infrared spherical lenses can be customized with various features to facilitate assembly and mounting, especially in space-constrained systems.

Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
