Glass Optical Properties Checker — Precision Optical Testing for Aviation & Defence
Jetsys Defence’s Glass Optical Properties Checker verifies optical clarity and structural reliability of aircraft windows, canopies, windshields and sensor covers. It measures spectral transmittance, reflectance, haze, clarity, refractive index, birefringence, wavefront error, striae, and wedge—giving maintenance teams and QA labs rapid, traceable results. An optional Glass Optical Properties Checker online reporting module turns lab data into shareable, audit-ready certificates.
What This Instrument Does
Spectral Transmittance (VIS/UV/NIR)
Measures how much light passes through glass to evaluate transparency and pilot visibility.Total / Hemispherical Reflectance
Assesses surface reflectivity for glare reduction, stealth performance, and optical signature control.Haze & Clarity
Quantifies scattering to ensure distortion-free pilot vision, critical for cockpit and canopy glazing.Refractive Index & Dispersion
Validates bending of light through glass—important for optical design, imaging paths, and HUD integration.
Retardation / Birefringence
Detects internal stress in formed, laminated, or tempered glass—prevents delamination or fracture risk.Wavefront Quality (PV / RMS)
Measures optical distortion for imaging, sighting systems, and Head-Up Display (HUD) beam paths.Striae & Homogeneity
Screens melt defects and refractive index variations to ensure uniform optical performance.Wedge Angle & Thickness
Verifies geometric accuracy to prevent double-vision and unwanted prism effects in mission-critical glazing.
Key Benefits of a Glass Optical Properties Checker
High-Accuracy Optical Certification
Delivers precise measurements of transmittance, reflectance, haze, clarity, refractive index, and birefringence—ensuring compliance with aerospace, defence, and industrial standards.Improves Pilot Visibility & Safety
Detects scatter, haze, and wavefront distortion to maintain crystal-clear cockpit visibility and HUD compatibility in mission-critical environments.Ensures Material Reliability in Harsh Environments
Validates optical performance after mechanical stress, heat, UV exposure, and aging for aircraft canopies, windscreens, domes, and windows.Quality Control for Laminates and Coatings
Detects delamination, AR-coating defects, tint shifts, and uniformity issues—ideal for laminated safety glass and specialty optical coatings.Detects Invisible Internal Defects
Identifies striae, inclusions, micro-bubbles, wedge and thickness errors that cause double-vision, ghosting, or distorted field of view.
Compliance with Aerospace & Defence Standards
Supports inspections to MIL, ISO, ASTM and aviation requirements—critical for OEM acceptance and flight-safety certification.Supports R&D and Failure Analysis
Helps engineers evaluate new materials, study ageing effects, surface processes, batch variations, and root-cause investigations.Reduces Rejection & Production Costs
Early defect detection prevents rework, scrap, production delays, and post-deployment failures.Works for Multiple Transparent Materials
Compatible with glass, acrylic, polycarbonate, laminated canopies, transparent armor, windshields, and coated optical substrates.
