Abstract
A laminated glazing for use as a combiner in a head up display comprises first and second glazing panes with at least one adhesive ply and an infrared reflecting film therebetween. Light incident upon the first glazing pane at an angle of incidence of 60° is reflected off the laminated glazing to produce first, second and third reflections, the third reflection being from light reflected from the infrared reflecting film. The laminated glazing further comprises light intensity reducing means between the first and second glazing panes for reducing the intensity of the third reflection. In an aspect, upon directing a beam of electromagnetic radiation having an intensity Iat 770 nm toward the first pane of glazing material at an angle of incidence of 60°, the intensity of the third reflection at a wavelength of 770 nm is less than or equal to 0.185×I.
