Excelitas graded reflectivity laser mirrors provide high damage threshold, spectral stability and precise spatial shaping of the intensity and phase characteristics of laser beams. With the use of proprietary precision Ion Beam Sputtered (IBS) technology, our graded reflectivity laser mirrors offer environmental stability and mechanical durability to meet the needs of demanding and harsh applications such as cavity optics in unstable resonator lasers.
Available in a wide range of sizes, these graded reflectivity mirrors are typically 0.25 inches (6 mm) to 5 inches (127 mm) and can be customized from virtually any substrate material including fused silica, optical glasses, ZnSe, ZnS and Si.
These laser mirrors can also be customized with any variation including non-rotationally symmetric patterns, as well as with complex designs which will increase and decrease the reflectivity repeatedly across the component. These mirrors include:

| Surface Flatness (@ 633 nm) | λ/20 |
| Surface Quality | 10-5 |
| Size Range | 0.25" to 5" |

| Humidity range | 0 to 100% |
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.
