The transmission spectrum of glass shows how light moves through it. This depends on the light’s color or wavelength. Learning about light’s behavior—bouncing, bending, and absorbing—helps engineers make better glass for things like solar panels and glasses. The type of glass and its thickness change how it works with light.
The transmittance of optical glass is measured using double beam spectral photometers from the company Perkin Elmer with special modifications. The standard setup enables to measure within a wavelength region from 250 nm up to 2500 nm. The measurement accuracy over the complete spectrum is about ±0.5%.
In this work, transmittance spectrograms of single glazing units at normal incidence were only measured, and a novel spectroscopic method was developed to determine the optical properties of single and double glazing units based on the transmittance spectra modeling.
When light enters glass, it slows down due to the material’s refractive index, which typically measures around 1.5. This slowing effect causes light to bend, a phenomenon known as refraction. The refractive index also determines how much light is reflected or absorbed, influencing the overall transmission spectrum of glass.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
