Automobile windscreen rake, spectacle lenses and effective transmittance

Research output: Contribution to journalArticle

Abstract

This study aimed to investigate the effect of windscreen rake angle on effective transmittance and the contribution of spectacle lenses to the total transmittance of the system. heoretical analysis has been carried out using the Fresnel reflectance equations. Windscreen rake can reduce effective transmittance significantly at angles present on modern aerodynamic vehicles. Spectacle lenses reduce the total transmittance still further, often to below the minimum level permissible in current international standards for windscreens.
