Optical Coating of Interference & Special Filters
Product Information
SCHOTT designs and offers customized coatings and has
e
­ xtensive capabilities to deposit thin films onto glass and
other substrates for spectral wavelengths between 200 nm
and 3000 nm using different technologies (e.g. ion assisted
deposition, magnetron sputtering).
Applications
Coated substrates and components are used in optical-, laserand illumination-systems, in the industrial sector, as well as in
applications in space, defense and medical.
Available coatings range from shortpass to longpass filters,
bandpass filters, bandblock filters and more:
•t irrors (high power laser mirrors, cold mirrors, etc.)
M
•t R-coatings (UV, VIS, IR wavelengths, or for specific waveA
lengths, combined AR & Hard coatings )
•t aser coatings with high resistance to flux
L
•t Dielectric beam splitters
•t Polarizers
The different coatings form various products used in
different applications:
•t Steep edge filters
•t Notch filters
•t Fluorescence excitation
•t Distance measurement
•t Digital imaging
•t Medical analysis
•t Process control
Materials
Various types of materials can be coated:
•t Optical glass
•t Fused silica
•t Glass ceramic (ZERODUR®)
•t Borosilicate glass (e.g. BOROFLOAT®33)
•t Optical filter glass

Specifications
•t Dimensions between 1 mm and 400 mm (diameter)
•t Coating of different supply forms and components
(e.g. prisms, lenses)
•t Spectral range between 200 nm and 3000 nm, according
to ISO 10110
•t Measurement accuracy: up to 0.05 %
Quality Assurance
Quality control is based on statistical process control as well
as on rigorous final inspection. Measurement instruments
i
­nclude a broad range of spectrophotometers, vision systems,
beam deflection, etc.
