Abstract
A coated glass article and a method for its production are provided. One or more coatings and layers are applied onto or disposed between a pair of glass sheets to produce such coated glass article that enhances an accuracy and reliability of a heads-up-display system and an optical sensor coupled thereto. More particularly, the coated glass article includes an antireflective layer to facilitate a light transmission of at least 80% for a plurality of wavelengths through the coated glass article and a visible light reflective layer to enhance a visible light reflectance of the coated glass article to between 8.0% and 10.0%.
Claims21
A coated glass article, comprising:
- a first glass sheet;
- an antireflective layer disposed adjacent at least a portion of the first glass sheet;
- and
- a visible light reflective layer disposed over at least a portion of the antireflective layer, the visible light reflective layer having a refractive index of at least 1.6 and a thickness of no more than 30 nm;
- wherein the coated glass article exhibits a light transmission of at least 80% for at least one wavelength of infrared light and a visible light reflectance of between about 8% and 10%.
A method of producing a coated glass article, comprising:
- providing a first sheet;
- disposing an antireflective layer adjacent the first sheet;
- and
- disposing a visible light reflective layer on at least a portion of the antireflective layer, the visible light reflective layer having a refractive index of at least 1.6 and a thickness of no more than 30 nm;
- wherein
- the coated glass article exhibits a light transmission of at least 80% for at least one wavelength of infrared light and a visible light reflectance of between about 8% and 10%.
A coated glass article, comprising:
- a first glass sheet;
- an antireflective layer disposed directly on at least a portion of the first glass sheet;
- and
- a visible light reflective layer disposed directly on at least a portion of the antireflective layer, the visible light reflective layer having a refractive index of at least 1.6 and a thickness of no more than 30 nm;
- wherein the coated glass article exhibits a light transmission of at least 80% for at least one wavelength of infrared light and a visible light reflectance of between about 8% and 10%.
