Anti-reflection coatings = anti-reflective glass = AR filter = anti-reflection filter = coatings which minimise the reflection on the lower boundary air/glass. In float glass, the reflection is reduced from approx. 4% to approx. 0.5% per boundary surface. This is accompanied by an increase in transmission of approx. 7 %.
There are anti-reflection coatings for larger wavelength ranges (broadband anti-reflection filters Type AR4) and for certain wavelengths (Type AR2 - specified wavelength).
| Borofloat / Float glass / Clear glass | 3 mm | from 20 x 20 mm to 1,080 x 800 mm |
| Borofloat / Float glass / Clear glass | 4 mm | from 20 x 20 mm to 1,080 x 800 mm |
| Borofloat / Float glass / Clear glass | 5 mm | from 20 x 20 mm to 1,080 x 800 mm |
In addition, we also provide even smaller filter sizes with less material thickness.
We can cut the filters round as well as in any other shape – please see Customised Glass Cutting Service.
Anti-reflective panes of glass are used for the composition of the polymer tank in 3D printers which, via a UV-curing polymer, provide the 3-dimensional structure, ensuring a high transmission of the UV light required for curing. The AR4 350-420 broadband anti-reflection coating used is optimised to allow the required UVA radiation to pass through.
Our filter types:
| Filter types | Reflection maximum | |
|---|---|---|
| AR4 350-420 | Antireflection in the near-UV range |
For surgical lighting, an anti-reflective and defined light-diffusing glass pane, type AR2-550 on gloss etched glass, for the visible light is used as the cover lens. It ensures high light efficiency, shadow-free work and a hygienic finish to the operating area.
Our filter types:
| Filter types | Reflection maximum | |
|---|---|---|
| AR2-550 | Reflection < 0.5% at 550 nm | 12 kB |
| AR4 | Reflection < 1% for λ= 450 nm - 650 nm | 12 kB |
Anti-reflective front glass protects costly laser beam-guiding optics in tough industrial use, e.g. type AR2-1064 on Borofloat for Nd:YAG welding lasers.
Our filter types:
| Filter types | Reflection maximum | |
|---|---|---|
| AR2-550 | Reflection < 0.5% at 550 nm | 12 kB |
| AR2-1064 | Reflection < 0.5% at the selected wavelength 1064 nm | 12 kB |
