PRECISION REFLECTANCE, ISOLATED
From coating R&D to full production, our reflectance solutions separate specular, haze, and ambient reflectance — so you measure exactly what matters.
COMPREHENSIVE SOLUTIONS FOR REFLECTANCE AND HAZE MEASUREMENT
Reflectance testing on flat and curved surfaces for advanced display technologies, architectural or automotive glass.
Our family of reflectance testing solutions delivers a clear, reliable picture of how reflectance affects real-world functionality and usability. By measuring first surface (specular) reflection separately or alongside haze and Lambertian reflection, we deliver more accurate, repeatable characterization under real environmental lighting conditions — giving manufacturers the control to solve everyday reflectance challenges and build better products.
Gamma Scientific’s high-sensitivity spectrometer delivers fast, accurate measurements, and when paired with comprehensive software for real-time and post-test analysis, testing and productivity gains follow. Solutions scale from benchtop transmission to semi-automatic gonioreflectance and fully automatic systems, supporting everything from R&D to manufacturing with improved quality control, streamlined processes, reduced costs, and increased reach.
Complete Reflectance Testing for Displays, Built for Accuracy and Repeatable Results
GS-191 REFLECTANCE MEASUREMENT SOLUTIONS FAMILY
The GS-191 family of reflectance testers optimize testing for AR coated glass, polished substrates, and diffuse surfaces. First surface reflectance on curved and flat surfaces provides real-world expectations for performance of everything from glasses to displays.
GS-291 AMBIENT REFLECTANCE COLOR TESTER
A modular, high-precision system that measures ambient light reflectance across numerous display types and form factors. As display sizes increase and geometries become more complex, sampling integrating spheres with custom integrated measurement ports have become the benchmark for flexible, accurate, and repeatable evaluation.
GS-391 VAAS HAZE, SPECULAR AND LAMBERTIAN REFLECTION TESTER FOR DISPLAYS
An automated solution for characterizing display and surface reflectance by independently measuring specular, haze and Lambertian reflection.
Test Applications for:
- Anti-Reflectance Coatings
- Architectural Glass
- Automotive Glass
- Eyewear Glass AR Coating
- Pyrolytic Glass Coating
- Display Technologies
- Optical filter/lens testing
- Characterization of flat panel displays, photovoltaic coatings, low-E architectural coatings, paint samples, and diffuse plastics
