Excelitas high-performance visible and infrared aspheric lenses offer a unique combination of high surface accuracy to achieve small, focused spot sizes and low surface roughness for minimal scatter and loss. These aspheric lenses feature sophisticated, multi-layer thin film coatings that deliver multispectral performance and a high laser damage threshold. Our aspheric lenses are produced with a densified structure to yield exceptional environmental stability making them ideal for demanding applications that require broadband or multispectral operation from the visible through the infrared, such as military range finding and target designation.
Excelitas UV and Visible aspheric lenses are produced using MRF technology. Our infrared aspheric lenses are manufactured utilizing single-point diamond turning technology, enabling highly accurate reproduction of virtually any rotationally symmetric aspheric shape. Diamond turning can also be used to create a surface diffractive phase profile allowing for more sophisticated functionality, such as the achromatization of single-element lenses.

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.
