Infrared & Ultraviolet Protective Safety Goggles

Overview

The CELI UV-IR Pro Goggles are engineered for precision optical safety in laboratory, industrial, and research environments where simultaneous protection against ultraviolet (UV) radiation (180–400 nm), near-infrared (NIR) radiation (780–1400 nm), and hazardous particulate exposure is required. Unlike generic safety eyewear, these goggles integrate a multi-layered optical defense system grounded in spectral absorption physics and ergonomic human factors engineering. The polycarbonate lens substrate—selected for its inherent impact resistance (meets ANSI Z87.1+ high-velocity impact requirements)—is coated with a proprietary DX-green interference filter that selectively attenuates UV-A/B/C and NIR bands while maintaining >85% visible light transmission (VLT) in the 400–780 nm range. This spectral selectivity ensures visual clarity without compromising photobiological safety during prolonged use under intense UV lamps, arc sources, or laser alignment setups.

Key Features

• Patented periorbital ventilation design: Micro-perforated brow bar with vertically aligned 0.3 mm apertures enables passive airflow across the ocular surface—reducing fogging by up to 40% compared to sealed-frame alternatives—while blocking direct line-of-sight UV/NIR irradiation via shadow masking geometry.
• Full circumferential protection: Extended side shields fabricated from the same optically matched polycarbonate resin as the primary lens eliminate lateral exposure pathways, meeting EN 166:2002 B-level splash resistance (tested at 10 mL/s flow rate) and ANSI Z87.1-2020 side impact criteria.
• DX-green anti-reflective & functional coating: A hard-coated, hydrophobic top layer provides Class A anti-fog performance (per ISO 17079:2021), chemical resistance to common solvents (e.g., acetone, ethanol, 10% NaOH), and certified UV/NIR attenuation: UV-B (280–315 nm) OD ≥4.0; UV-A (315–400 nm) OD ≥3.5; NIR (800–1200 nm) OD ≥2.5.
• Adjustable anthropometric fit system: Dual-axis temple adjustment—vertical pivot (±15°) and telescoping length (four discrete stops: 125 mm, 130 mm, 135 mm, 140 mm)—accommodates facial dimensions across the 5th–95th percentile of ISO 13555:2016 headform standards, ensuring consistent seal integrity and pressure distribution.

Sample Compatibility & Compliance

These goggles are validated for use with UV-C germicidal lamps (254 nm), mercury-xenon arc sources (200–2000 nm), and NIR-emitting diode arrays used in spectroscopy and phototherapy calibration. They comply with international occupational safety standards including ANSI Z87.1-2020 (impact, optical density, flammability), EN 166:2002 (optical class 1B, mechanical strength), and ISO 12312-1:2013 (solar radiation filtering). Documentation includes full test reports traceable to NIM (National Institute of Metrology, China) accredited laboratories. While not classified as medical devices under FDA 21 CFR Part 820, the design supports GLP-compliant documentation workflows through serialized batch labeling and material traceability down to resin lot level.

Software & Data Management

No embedded electronics or firmware are integrated—consistent with passive PPE regulatory classification. However, each goggle unit carries a laser-etched serial code enabling integration into enterprise asset management systems (e.g., SAP EHS, Intelex). CELI provides a downloadable PDF-based Optical Performance Certificate (OPC) per batch, containing spectrophotometric transmittance curves (200–1500 nm), impact test videos, and coating durability data (Taber abrasion cycles, ASTM D1044). Optional digital twin support is available via API integration with LIMS platforms for automated PPE lifecycle tracking and replacement scheduling based on cumulative UV exposure estimates.

Applications

• UV crosslinking and photopolymerization in semiconductor cleanrooms
• NIR spectroscopy source alignment and detector calibration
• Photocatalysis reactor monitoring (e.g., TiO₂ activation under 365 nm UV LEDs)
• Plasma etching chamber maintenance under broadband UV/VUV emission
• Forensic UV fluorescence examination requiring unfiltered visible contrast

FAQ

What is the optical density (OD) rating for UV-C (254 nm) radiation?
OD ≥4.0, verified per ISO 17166:2019 using calibrated spectroradiometry.
Can these goggles be worn over prescription eyewear?
Yes—the frame depth (12.5 mm orbital clearance) and adjustable temples accommodate most ANSI Z87.1-compliant prescription inserts.
Is the DX-green coating resistant to repeated alcohol-based disinfection?
Yes—validated for ≥50 cycles of 70% isopropyl alcohol wipe-down without measurable transmittance shift (ΔT < 0.5%).
Do they meet FDA requirements for use in clinical phototherapy settings?
They satisfy optical safety requirements of IEC 62471 (Photobiological Safety of Lamps) for Risk Group 2 (RG2) sources but require institutional risk assessment per local health authority protocols.
What is the service life under continuous UV exposure?
Based on accelerated aging (QUV testing per ASTM G154), lens optical performance remains within specification for ≥2,000 hours of simulated UV-B exposure at 0.68 W/m² @ 313 nm.
