For Reflectance Measurement on Glass Coatings
The ColorXRA G3 non-contact reflectance spectrophotometer measures color quality on multi-silver layers on coated glass and other non-scattering samples in the lab and inline throughout production.
Since glass is non-scattering, conventional measurement devices with direct illumination cannot provide accurate color data. The ColorXRA G3 measures from 330 nm to 1,000 nm with 1 nm optical resolution. In the lab, the device can be mounted on a stand to measure a glass pane laying on a sample support. To measure inline, the ColorXRA G3 can be mounted on a traversing beam above the pane to measure low-e glass and below the pane for the measurement of sun protection coatings.
The ColorXRA G3 is a compact multi-angle spectrophotometer that measures from 330 nm to 1,000 nm with 1 nm optical resolution. It is mounted 10 mm from the glass pane and captures spectral data as well as color in reflectance on non-scattering samples at 3 different angles to qualify even multi silver layer coatings.
The ColorXRA G3 uses a Xenon flash lamp to take measurements every second on non-scattering products such as coated glass using three geometries simultaneously at +15°: -15°, +45°: -45° and +60°: -60°. The ±15° measurement gives the same readings as in the laboratory with a sphere geometry measurement. The ±45° and the ±60° measurements show color change from different observer angles.
The 1 nm resolution spectra data from 330 nm to 1,000 nm provide reliable information to control the coating process.
Uses real dual beam measurement and automatic wavelength calibration. Only requires external calibration every 4 weeks for maximum uptime.
Built with durability in mind, the ColorXRA G3 is rugged enough to endure busy labs and production lines without compromising measurement accuracy.
