Excelitas offers high-energy laser mirrors that provide an unmatched combination of high laser damage threshold, ultra-low scatter, excellent wavefront performance, and rugged mechanical durability. With the use of proprietary superpolishing fabrication and precision Ion Beam Sputtered (IBS) technology, our high-energy laser mirrors are highly reflective and environmentally stable to meet the needs of demanding applications such as military targeting and range finding, industrial materials processing systems, intracavity laser use and high-energy research lasers.
Custom fabricated and coated, our high energy laser mirrors have typical specifications of 99.99% reflectivity, λ/20 flatness (at 633 nm), 10-5 surface quality, and scatter loss of 1 part per million at certain wavelengths. They are available in a wide range of sizes and shapes, typically 0.25" to 10" in diameter, and can be customized from virtually any substrate material, including fused silica, optical glasses, Zerodur and Pyrex. These mirrors are designed primarily for use with pulsed, solid state lasers operating at 1064 nm, 532 nm and 355 nm, as well as for use with multi-spectral laser 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.
