Abstract: A fractioning device for an ion implantation device with at least one fractioning wall, wherein the fractioning device is suitable for being inserted within a channel. The channel is configured to connect an ion source, which is at a first pressure p1 and a processing chamber, which is at a second pressure p2 in an ion implantation device.

Abstract: Substrates that can act as optical elements for transmitting infrared light and that have low reflectance for infrared light and the assembly of such substrates with a source of infrared light and/or with an infrared-sensitive optical component. The substrates are suitable for cover glasses and optical elements, such as lenses, prisms, or mirrors to be used with infrared light. Ions are implanted into a substrate in order to reduce its reflectance of infrared light.

Abstract: A glass sheet comprising at least one antireflective, etched surface having a surface roughness defined, when measured on an evaluation length of 12 mm and with a Gaussian filter with a cut-off wavelength is 0.8 mm, by: 0.02?Ra?0.6 ?m; 0.1?Rz?3 ?m; and 5?RSm?180 ?m. The glass sheet has the following optical properties, when measured from the antireflective, etched surface: a haze value of from 1 to 40%; a clarity value of from 30 to 100%; a gloss value at 60° of from 20 to 130 SGU; and a luminous reflectance Rc from 4 to 7%. The antireflective, etched surface comprises implanted ions. Such a glass sheet is particularly suitable for display applications as cover glass and has excellent sparkle reduction properties together with an anti-glare effect.
