Excelitas CO2 Laser Lenses

Excelitas high-precision infrared CO2 laser lenses are customized from a variety of substrate materials, including Ge, ZnSe, ZnS, and Cleartran. Using our substrate fabrication and coating leading-edge process technologies, our CO2 laser lenses minimize subsurface damage for excellent Laser Damage Thresholds.

Excelitas consistently delivers optics with exceptional laser damage resistance characteristics due to our highly controlled processes for fabricating, coating, and laser-damage testing in our state-of-the-art facilities, with a unique capability of in-house laser damage testing. This vertical integration is critical for enabling careful control over every aspect of the design and manufacturing process to achieve a high damage threshold reliably. This process includes precise specification and thorough inspection of incoming raw materials, followed by shaping and polishing the components to minimize subsurface damage and contamination. Thin film coatings are then designed and deposited using our techniques that avoid contamination and limit electric field effects. In addition, our broad well-equipped in-house laser damage testing lab includes several different laser pulse widths and wavelengths.

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.
