Excelitas CO2 Mirrors

Excelitas offers a range of copper high reflectors designed for use with high-power CO₂ lasers to enable beam delivery and beam shaping. These laser mirrors offer a combination of high reflectivity >99.7% at 10.6 μm, excellent surface quality (40-20) and low scatter with surface roughness <50Å. Produced from oxygen-free, high thermal conductivity (OFHC) copper, these reflectors deliver superior optical performance and maximum laser damage threshold.

These CO₂ laser mirrors can be fabricated with plano, spherical or cylindrical surfaces and can range from 6 mm to 150 mm in size. Through the use of holes, mounting flanges and other mechanical features can be easily accommodated. In addition, Excelitas can employ its traditional electron beam (e-beam) or Advanced Plasma Source (APS) coating technologies in order to deliver the precise combination of durability, damage resistance and cost characteristics required for a specific application. Furthermore, the optics are handled in a controlled environment throughout the manufacturing process, thus preventing any deterioration of the pristine optical surfaces prior to coating, and maximizing thin film adhesion and laser damage threshold.

Frequently Asked Questions

What is the typical lead time for gas turbine overhaul services?

The lead time for gas turbine overhaul services ranges from 6 to 14 weeks, depending on the damage assessment, parts availability, and whether hot-section repairs are required. Expedited options may reduce this by 30%.
Do you provide customizations for legacy turbine control 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.
How often should industrial gas turbines undergo performance testing?

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.
Are your radiation-hardened (rad-hard) semiconductors compliant with MIL-PRF-38535?

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.
What temperature ranges do your military-grade ICs support?

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.
Are PMA parts interchangeable with OEM components?

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.
What traceability standards do you follow for aircraft fasteners?

All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
How do you handle urgent AOG (Aircraft on Ground) requests?

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.
