Übersetzung für "Basisglas" in Englisch

The underlying glass can be clear, extra clear, coloured, reflecting or patterned.

Its coating has higher emission properties than those of the iplus E basic glass.

For example, the base lens can be a conventional blank or semi-finished product.

Interpane Glasgesellschaft also produces coated basic glass.

As base glass for the entire building project EUROWHITE was used.

Thanks to the use of EUROWHITE NG as the basic glass, the triple insulation glazing provides maximum transparency.

Semifinished articles are fashioned as cylindrical rods from the base glass after casting by grinding and polishing.

Different advantageous constructions for the base glass according to the invention are described in the following first nine examples.

Coated glass is a basic glass which has undergone a surface treatment or coating (applied under vacuum using an electromagnetic process [23]) designed to eliminate reflections or ensure thermal insulation.

At the various Glas Trösch plants in Switzerland, Germany and the Ukraine, basic glass is processed by a wide range of means for the EXTERIOR Division.

At the same time, the insulating glass still allows plenty of natural light to enter the rooms thanks to the use of EUROWHITE NG as the basic glass.

High-performance basic glass for the construction and solar markets are supplied to southern Germany, Austria, Switzerland, Italy, Spain and south-eastern Europe.

The coloured SWISSLAMEX COLORDESIGN laminated safety glass and as base glass the colour-neutral EUROWHITE NG were used for the fresh green glass roofs.

Aluminoborosilicate glass according to claim 1, wherein the base glass contains between 15 and 30 mole % of M 2 O, preferably Na 2 O.

Aluminoborosilicate glass according to claim 1, wherein the base glass further comprises Ag 2 O in a concentration of up to 2 mole %.

In the production of spectacle lenses to be adapted to the prescription data of a spectacles wearer, a suitable semi-finished spectacle lens can be selected and the surface opposite to the surface with the base grating can be processed depending on the prescription data of the spectacles wearer.

Within the scope of the present application, a base lens can be any optical element that has at least one diffraction grating.

The base lens can also be a so-called compound system, which has at least one main lens and one cover lens.

It is also possible that the base lens is a compound system comprising at least one main lens and one cover lens.

The base lens can be a so-called compound system, which has at least one main lens and one cover lens.

Depending on the obtained prescription data or on the target power of the spectacle lens, a base lens is selected, the partial power range of which corresponding to the obtained prescription data (in particular the spherical prescription power) or the target power of the spectacle lens in the at least one predetermined reference point.

Each base lens of the series has a base power different from the base powers of the other base lenses of the series, and has at least one diffractive base grating.

They are outstandingly suitable for use as component glass in optical data transfer systems, especially as a base glass for pick-up lenses, because of the property profile.

In order to obtain sufficient adherence of the optical coating on the base glass, the material must contain organic binding or strongly adhesion-promoting ingredients in sufficient amounts.

The invention is directed to an aluminoborosilicate glass containing alkali metals and at least a partial volume of silver ions that are introduced into a base glass of silicon oxide, boron oxide, aluminum oxide and at least one alkali metal oxide by ion exchange with alkali metal ions, particularly for gradient index lenses (GRIN lenses), and to a method for the production of GRIN lenses and other optical elements with an at least partially increased or reduced index of refraction.

It cannot be determined whether or not the tendency toward crystallization is also sufficiently reduced. Further, for the production of GRIN lenses WO 02/14233 A1 describes alkali-free borosilicate glasses with a high silver content in which the high silver content (of at least two cation percent) is present in the base glass by means of block melt without the addition of alkali ions.

The invention makes it possible to realize the production of GRIN lenses based on aluminoborosilicate glasses in which the base glass, particularly in the thermal treatment steps for generating higher refractive indices and refractive index gradients, has an appreciably reduced tendency toward crystallization while retaining the positive characteristics of conventional borosilicate glasses such as meltability at temperatures conventionally used in glassmaking (up to 1600° C.) with good optical quality and a high index of refraction after the introduction of silver without substantial coloration.

However, crystallites can already exist in the base glass when the melt solidifies or can form or possibly grow in the subsequent ion exchange process. GRIN Spherical Lenses
