Optical Glass Coatings

Optical Glass Coatings Product Information

SCHOTT Advanced Optics performs standard and custom-designed optical glass coatings. We deposit optical thin film coatings onto glass and other substrates for spectral wavelengths between 200 and 3000 nm.

Important optical glass coating types include:

Reduce reflection: Anti-reflective (AR) coating, spectral range in UV, VIS, IR
Increase reflection: mirror coating (metallic or dielectric)
Beam splitters
Polarizers
Neutral density filter coating
Laser coating with high resistance to flux
Demist coating RIA 2
Bandpass Coating
ITO coating
SIO2 protective coatings

”Hard coatings” do not need any additional protection, because the layers usually consist of very stable metal oxides. ”Soft coatings” usually require additional measures to protect the filters. This can be achieved by a supplementary cementing with a suitable glass.

Within certain areas of the UV spectrum it is not possible to use optical elements due to the inherent absorption involved. In such cases the coated substrates are fitted into appropriate mounts and protected by suitable glass.

Optical Glass Coatings Benefits

SCHOTT Advanced Optics is a trusted supplier of coated products due to our long experience and reliable process stability. With our expertise, we can provide:

Different types of optical glass coating on substrates of different sizes and materials
Different values for half width (HW)
Continuously alterable half widths (i-line filters, band passes)
Ion plating: specific temperature stability possible

Optical Glass Coatings Key Applications

Optical glass coatings are often required for substrates used in:

Optical systems

Laser systems

Illumination

Space applications

Defense applications

Medical applications

Industrial sectors.

Optical Glass Coatings Materials

All types of materials can be coated:

Borosilicate glass
Contrast enhancement glass types, etc.
Filter glass
Optical glass
ZERODUR^® glass ceramic

Forms of Supply

Our standard forms of coated substrates range from 1 mm to 400 mm. Larger dimensions, such as 900 x 900 mm, AR and Aluminum mirror plates are also available.

Optical Glass Coatings Specifications

We can coat substrates with diameters between 1 mm and 400 mm. The spectral range is between 200 and 3000 nm. Since a very broad range of specifications can be met, please use the bandpass-, longpass-or shortpass-filter questionnaire in the interference filter catalog.

Plasma Assisted Deposition with the Leybold-Advanced Plasma Source (APS)
Cold electron beam evaporation

Quality Assurance

We measure the quality of our optical glass coating with a spectrophotometer (measurement between 200 nm and 3000 nm), and also conduct direct or indirect monochromatic monitoring with quartz crystal and optical thickness measurements.

We can also deliver test glasses upon request.
