ULO Optics CO₂ Laser Optical Components and Consumables

Overview

ULO Optics CO₂ Laser Optical Components and Consumables represent a comprehensive, ISO 9001–certified portfolio of precision infrared optics engineered specifically for continuous-wave (CW) and pulsed CO₂ laser systems operating at the 10.6 µm wavelength. Designed and manufactured in the UK since 1982, these components leverage fundamental principles of mid-infrared (MIR) optical physics—including Brewster-angle transmission, high-reflectivity dielectric stack design, and thermal-lens-resistant substrate geometry—to ensure stable beam propagation, minimal wavefront distortion, and long-term power handling integrity. The product line serves both OEM integrators developing industrial laser cutting, welding, and surface treatment systems, as well as end-users requiring field-replaceable optics for maintenance, recalibration, or process optimization. All elements are fabricated from industry-standard MIR-transmissive materials—including zinc selenide (ZnSe), germanium (Ge), silicon (Si), and oxygen-free high-conductivity (OFHC) copper—with strict control over surface flatness (λ/10 @ 633 nm), scratch-dig quality (40–20), and coating adhesion per MIL-C-48497A.

Key Features

• UltraLO AR/AR anti-reflection coatings optimized for >99.5% transmission at 10.6 µm, with damage thresholds exceeding 10 MW/cm² for CW operation and >1 J/cm² for nanosecond pulses
• Customizable substrate geometries: plano-convex, meniscus, cylindrical, axicon, telecentric, and aberration-corrected designs for focused spot stability and minimal focal shift under thermal load
• Water-cooled mounting solutions (WMA/WMB/WMD series) rated for continuous operation at up to 5 kW laser power, featuring integrated O-ring seals and standardized flange interfaces (ISO-KF, CF)
• Gas nozzle assemblies (SNA/MNA/LNA/GNA series) with precision-machined orifice profiles and thermal expansion-matched mounting for consistent assist gas laminarity in cutting applications
• High-durability metallic mirrors: Cu ‘Goldmax’ (Au over NiP on OFHC Cu) and Cu ‘Supermax’ (dielectric-enhanced Au) offering >98.5% reflectivity and superior oxidation resistance in humid or particulate-rich environments
• Zoom-optic families (ZX10, BEZ5–BEZ30, SLZ25, GPZ25) enabling dynamic beam resizing without mechanical realignment—critical for adaptive processing and multi-material parameter tuning

Sample Compatibility & Compliance

ULO CO₂ optics are compatible with all major industrial CO₂ laser platforms—including Trumpf, Bystronic, Prima Power, and Coherent—across standard cavity configurations (stable/unstable resonators) and beam delivery architectures (articulated arms, fiber-coupled hybrid systems, galvo-based scanners). Substrate material selection adheres to ASTM F1632 (ZnSe transmittance verification), ISO 10110-7 (surface quality specification), and IEC 60825-1 (laser safety compliance for optical component classification). All coated optics undergo environmental stress testing per MIL-STD-810G (thermal cycling: –40°C to +85°C; humidity: 95% RH at 40°C; vibration: 10–2000 Hz, 0.04 g²/Hz PSD). Documentation supports GLP/GMP traceability, including lot-specific coating spectral data, interferometric surface maps, and RoHS/REACH declarations.

Software & Data Management

While ULO Optics components are passive optical elements and do not incorporate embedded firmware or onboard software, full technical documentation is provided in machine-readable formats (PDF, STEP, Zemax .zmx) for integration into optical design workflows (e.g., Zemax OpticStudio, CODE V, FRED). Each shipment includes a Certificate of Conformance (CoC) with metrology data traceable to NPL (UK National Physical Laboratory) standards. For customers implementing automated inventory or calibration management systems, ULO supports structured data exchange via CSV export of part-level specifications—including radius of curvature, thickness tolerance, coating spectral curves, and thermal conductivity values—for import into CMMS or LIMS platforms. Audit trails for coating batch records comply with FDA 21 CFR Part 11 requirements when used in regulated medical device manufacturing processes.

Applications

• Industrial material processing: high-speed sheet metal cutting, non-metallic composites ablation, ceramic scribing, and polymer welding with controlled heat-affected zone (HAZ) minimization
• Scientific instrumentation: Fourier-transform infrared (FTIR) spectrometer beam splitters, cavity ring-down spectroscopy (CRDS) mirrors, and quantum cascade laser (QCL) collimation optics
• Medical laser systems: dermatological resurfacing, soft-tissue ablation, and dental hard-tissue procedures requiring precise 10.6 µm energy delivery
• Aerospace & defense: IR countermeasure (IRCM) window assemblies, laser radar (LADAR) transmitter optics, and directed-energy weapon (DEW) beam shaping subsystems
• Research & development: ultrafast CO₂ amplifier seeding, parametric oscillation experiments, and mid-IR frequency comb stabilization optics

FAQ

What substrates are available for high-power CO₂ laser applications?

ULO offers ZnSe, Ge, Si, and OFHC copper substrates—all qualified for average powers ≥3 kW and peak intensities ≥1 GW/cm² depending on geometry and cooling configuration.
Do you provide custom coating specifications beyond standard UltraLO AR/AR?

Yes—custom high-reflectivity (HR), partial reflectivity (PR), polarizing, and broadband MIR coatings can be engineered per customer-defined spectral bands (9–12 µm), angle of incidence (AOI), and polarization state.
Are water-cooled mounts compatible with third-party laser heads?

All WMA/WMB/WMD mounts conform to ISO 10110-1 mechanical interface standards and include metric thread patterns (M30×1.5, M42×2) for direct retrofit onto TRUMPF TruFlow, Bystronic ByStar, and IPG YLS series laser sources.
Can scanning lenses be used in galvanometer-based systems requiring telecentricity?

Yes—the LSM series scanning mirrors and telecentric f-theta lenses (e.g., 48TSL, SES/15/xxx) maintain ≤±0.1% field curvature across 200 mm × 200 mm scan fields at ±20° galvo deflection.
Is ZnSe window certification available for ISO 13485 medical device manufacturing?

ULO provides optional ISO 13485-compliant documentation packages—including biocompatibility test reports (ISO 10993-5 cytotoxicity), particulate shedding analysis, and sterilization validation data—for ZnSe windows used in Class IIa/IIb laser surgical devices.
