Optical Windows, Light Transmitting Optics

Flat windows made of optical & technical quality glasses

We manufacture optical windows for technical-optical applications. For this type of optics we only use high-quality and very pure glass materials. This ensures high imaging quality, keeps optical distortions small and ensures a good optical transmission. Below you will find links to a selection of our optical glasses and materials with further information:

Optical Windows:

 

N-BK7 windows

BK7 is the industry standard for optical quality windows for applications in the visible wavelength range. All types of optics, such as windows, lenses, prisms or optical flats are made from BK7. more...

 

Quartz Glass & Fused Silica windows

Our optical windows made of synthetic, optical quartz glass offer a very high transmission in the UV range. Already at a wavelength of 185 nm, more than 80% of transmission is available. Operating temperatures up to 1000 °C are possible with this material. more...

 

BOROFLOAT® windows

The high-quality borosilicate glass BOROFLOAT® has a temperature resistance of up to 500 °C. It provides good optical quality, low absorption and exceptionally high chemical resistance. more...

 

B 270® - Superwite windows

B 270® is a clear crown glass with very good light transmission. The optical quality of the natural blank surfaces is only moderate according to optical standards. However, high-grade optical windows can be produced from this glass by means of an optical polish. more...

 

Selected float windows

Our selected float glass is cost-effective and has a high surface quality and flatness with "mirror glass quality". It provides good optical transmission in the visible. The glass is an ideal choice for applications with increased optical requirements compared to normal glass. more...

 

 

Thin- and Ultra Thin Optical Windows:

 

D 263 T windows

D 263 T is a perfect material for thin and ultra-thin glass windows. Even at low thickness, the glass has a remarkable flatness* and a low warpage. For rectangular designs, we manufacture windows with a thickness of only 50 μm from D 263 T. Round and free shapes are possible beginning at 0,1 - 1,1 mm thickness. more...

 

1737F windows

1737F is an alkali-free boro-aluminum silicate glass with a low micro-roughness suitable for COG (chip on glass) processes. It has a good flatness* and surface quality. more...

 

EAGLE2000 windows

EAGLE2000 is a lightweight and practically alkali-free glass. It has display glass quality and even allows more demanding applications. The glass is color neutral and can withstand elevated temperatures. more...

 

MEMpax® windows

MEMpax® is a borosilicate thin glass with almost the same thermal expansion as BOROFLOAT®. It has a better surface quality and planarity* than most mechanical polishes can achieve at small glass thicknesses. more...

 

AF 32® eco windows

The new, alkali-free thin glass AF 32® eco is used in micro-optic and optoelectronic applications. It can withstand temperatures up to 600 °C and features a high optical transmission and surface quality. more...

 

AS 87 eco windows

AS 87 eco is an ultra-thin aluminosilicate glass which still has a quite good transmission at upper UV-wavelengths. The glass is limited flexible and suitable for thin windows in optoelectronics. AS 87 eco has a good optical quality and a low micro-roughness. more...

 

*Note: The optical flatness of thin and ultra-thin windows is limited for physical reasons. The planarity depends directly on the thickness of the glass in the case of a thin glass, since with low glass thicknesses, the inherent mass of a glass has an influence on the flatness. Very high flatnesses, as are possible with thicker glasses, can generally not be achieved with thin glasses. The windows, which are made from the aforementioned thin glasses, in most cases represent the best possible choice for the best possible planarity at such low glass thicknesses.

 

 

Coated Windows:

 

ITO-coated optical windows

Our ITO-coated glass windows have a thin, optically transparent and electrically conductive indium-tin oxide coating on one or both surfaces. more...

 

Multilayer broadband anti-reflective coated windows

Antireflection-coated windows prevent reflections on the surfaces of the substrate glass. They are used to eliminate ghost images or to reduce the optical attenuation. more...

 

 

Customized Optical Windows:

We manufacture optical glass windows in almost any form from almost any kind of glass on request. Each optical window can be polished to a particular flatness and surface quality. Coatings, for example an antireflection coating for a specific wavelength, are also possible on the basis of a coating run.
