Product Variants of Optical Coatings
With more than 30 years of experience in optical coatings, SCHOTT has a vast range of interference filters, which includes specific variants that serve a series of complex applications. These variants include High Power Laser filters, Anti-Scratch Hard AR, Edge and Bandpass Filters and UV Bandpass Filters.
High Power Laser
High Power Laser
SCHOTT offers coatings that are suitable for high power lasers and can be used for a variety of applications in laser processing, medicine and research. Modern coating technologies such as E-Beam, IAD and IBS are applied to a wide range of optical components such as aspheres, windows and prisms, with the resulting laser coatings offering the lowest losses and highest laser-induced damage thresholds (LIDT).
YOUR ADVANTAGES
- High Laser Induced Damage Threshold (LIDT).
- Low-loss anti-reflective and mirror properties.
- Broad applicable wavelength range from λ 266-1560 nm.
Anti-Scratch Hard AR
Anti-Scratch Hard AR
Providing unparalleled scratch resistance and a surface hardness comparable with sapphire, our range of hard anti-reflective coatings ensure the performance of your optical system even in the harshest conditions.
CHARACTERISTICS
Our patented scratch-resistant hard AR coating can be applied to SCHOTT Sapphire glass to improve light transmission without sacrificing the robustness of the material, as well as optical and technical glasses such as BOROFOLOAT 33® & Xensation® in order to greatly enhance the robustness of these materials.
YOUR ADVANTAGES
- Applicable to a wide range of materials, including SCHOTT BOROFLOAT 33®, N-BK7®, Xensation® and Sapphire.
- High blocking up to OD > 6.
- Wide applicable wavelength range from λ 400-1600 nm.
- Available as broad band AR or wide angle AR coating.
- Low reflectivity down to < 0.5%.
- Conforms to MIL-STD 675c and MIL-STD-810 standards.
Edge and Bandpass Filters
Edge and Bandpass Filters
We offer a wide range of filters to improve your imaging contrast and enhance the signal-to-noise ratio for applications in the fields of machine vision, automation and life sciences.
CHARACTERISTICS
Our portfolio encompasses narrow bandpass and steep edge short- and longpass filters from the UV to the NIR ranges. Utilizing IAD and sputtering techniques, we ensure our filters have the highest precision and durability.
YOUR ADVANTAGES
- High transmission for the passband T > 95% from VIS to NIR.
- High Blocking > OD 5.
- Wide blocking range from λ 200-1200 nm.
- Tight center wavelength tolerances down to +/- 0.3%.
- Edge tolerances smaller than +/- 0.5%.
- Able to combine with filter glasses for enhanced blocking > OD 8.
UV Bandpass Filters
UV Bandpass Filters
Our UV bandpass filters for the analysis of fluids and gases deliver long-term reliable performance for a broad range of spectroscopic applications. These rugged assembled filters provide high blocking outside the narrow bandpass to ensure a high signal-to-noise ratio.
YOUR ADVANTAGES
- Narrow bandpass with FWHM 6-15 nm.
- Passband transmission of 15-30% within λ 200-350 nm.
- Tight center wavelength tolerances down to +/- 0.5 %.
- High blocking of typical OD > 4 within a blocking range of λ 200-600 nm.
Low defect
Low defect
Combining our experience and expertise in filter glass with our extensive coating range allows us to provide low-defect AR and UV-cut solutions for cover glasses in CCD and CMOS sensors. Our low-defect coatings are optimized to significantly enhance the environmental durability of SCHOTT BG Filter glasses.
YOUR ADVANTAGES
- AR coating with typical R < 0.5% from λ 200-700 nm.
- UV-cut coating with edge position < 430 nm and tolerance +/- 6 nm.
- High environmental durability with BG-Filter glasses such as BG55.
Laser Blocking Filters
Laser Blocking Filters
These blocking filters provide the necessary protection for sensitive sensor arrangements or guard the human eye from harmful laser radiation. These filters are used in optronic sensor systems and periscopes for surveillance, detection and target acquisition, providing high blocking of laser wavelengths without sacrificing transmission and color accuracy.
YOUR ADVANTAGES
- High transmission for the passband T > 95% from λ 400-560 nm.
- High blocking up to OD > 6.
- A wide blocking range, from λ 200 nm up to 5 µm.
- Tight center wavelength and edge tolerances.
- Able to combine with filter glasses for enhanced blocking > OD 8.
- Able to combine with Anti-Scratch Hard AR coatings for improved durability.
HMD / HUD Combiner
HMD / HUD Combiner
In head-mounted or head-up displays, SCHOTT coatings enable flat and curved combiner optics to directly project crucial information into the field of view without blocking outside visibility. Notch filters can also be applied on glass and plastic substrates, with very high uniformity to ensure perfect contrast and brightness over the whole display area.
YOUR ADVANTAGES
- High photopic transmission greater than 80%.
- High contrast over the entire projection area.
- Lowest color distortion of the outside for enhanced perception.
