2. Window film - Wikipedia

   en.wikipedia.org/wiki/Window_film

   The thicker window films known as safety and security window film are designed to perform under extreme conditions, and as such there are specific standard criteria these films should meet, such as American standards ANSI Z.97, CPSC 16 CFR 1201, Cat II (400 ft-lb), and the British Standards BS 6206 (Class A, B, C).

3. Anti-reflective coating - Wikipedia

   en.wikipedia.org/wiki/Anti-reflective_coating

   An anti-reflection coated window, shown at a 45° and a 0° angle of incidence There are two separate causes of optical effects due to coatings, often called thick-film and thin-film effects. Thick-film effects arise because of the difference in the index of refraction between the layers above and below the coating (or film ); in the simplest ...

4. Safety and security window film - Wikipedia

   en.wikipedia.org/.../Safety_and_security_window_film

   The film thickness is selected for level of protection desired and the dimensions of the glass pane. Manufacturers recommend 100 micrometer film (2 ply) for glass up to 3 mm (1/8 in) and 175 micrometer film for glass over 6 mm (1/4 in). These films can be applied for security applications, where a delay of forced entry is desired.

5. Picture framing glass - Wikipedia

   en.wikipedia.org/wiki/Picture_framing_glass

   While "anti-glare" (a.k.a. "non-glare" or matte finish) glass treatments focus on scattering the light, "anti-reflective" coatings actually reduce the amount of light, which is reflected from each glazing surface, which has the benefit of increasing the amount of light transmitted through the glazing.

6. See-through graphics - Wikipedia

   en.wikipedia.org/wiki/See-through_graphics

   Perforated films were sold in the 1970s and 1980s as sun blinds for vehicles and buildings. This was cited in the first patent application for see-through graphics. [4] The blinds had brightly colored and reflective front sides. The reverse side was a non-reflective black color which allowed good visibility through the blind.

7. Smart glass - Wikipedia

   en.wikipedia.org/wiki/Smart_glass

   Some effects can be obtained by laminating smart film or switchable film onto flat surfaces using glass, acrylic or polycarbonate laminates. [9] Some types of smart films can be applied to existing glass windows using either a self-adhesive smart film or special glue. [ 10 ]
