Please find a summary of our standard optical thin-film coatings for many applications on this page. We regularly do the vacuum vapor, ion-beam, and sputter deposition of the listed thin films to guarantee the best availability, even for custom-sized parts. Please consider using the links below to view the datasheets with all specifications and properties of our standard thin-film coated materials:
We produce and process electrically conductive and transparent indium tin oxide thin films deposited by sputter deposition on various high-quality substrates. This sputtering process provides excellent micro-roughness of the ITO films on a level other deposition processes can't offer. Customized sputtering of ITO coatings with a surface resistivity between 5 Ω/square and 1 kΩ/square is possible for production quantities on request. We also fabricate numerous ITO coatings on exotic substrate materials like alkali-free, quartz, and thin glasses.
Our ARC coating is an efficient multi-layer anti-reflection thin film coating that significantly reduces reflections and suppresses double images. The materials offer significantly increased transmittance and much lower energy loss than uncoated glasses. We deposit the ARC-thin films on selected quality substrate materials. The deposition of materials provided by the customer is available for sufficiently large production quantities.
A high transmission characterizes our ARC-O anti-reflection coatings, which feature an additional oleophobic coating on the operator side. The grease-, liquid-, and dirt-repellent coatings reduce fingerprints to a minimum.
The SEA-VIS mirror has an aluminum-metal thin film coating with dielectric overcoatings, which we optimized for increased reflectivity in the visible area. The first surface mirror coating is vacuum-deposited on selected float glass substrate materials. The SEA-VIS is economically priced and offers excellent optical quality and mechanical stability. It can also be used in laser applications to reflect lasers with low to medium laser power.
Our SEA-NIR front surface mirrors have the same basic design and substrate material as the SEA-VIS series. We optimized the dielectric layers on top of the metal thin film coating for applications that need to reflect near-infrared wavelengths.
The SEA-UV metal front surface mirrors are protected by a very thin SiO₂ layer coated above the metallic layer. This quartz coating ensures superb ultraviolet reflectivity and, at the same time, broadband reflectivity up into the IR range.
The SHP has a silver metal coating with powerful reflectivity. It works with polarized and unpolarized light and laser radiation in the visible wavelength range.
The SHR is a metal-free performance mirror with very high reflectivity in the visible based on purely dielectric thin films. It is suitable for unpolarized light applications requiring an angle of incidence of 45°. The SHR thin films can also be used for specific laser applications and withstand a high thermal load.
We designed the thin film coatings of our dielectric SHP-D front surface mirrors for excellent reflectivity for S & P polarized and unpolarized light at visible wavelengths and a wide range of incidence angles. We achieve the outstanding performance of the SHP-D coating by depositing numerous thin-film layers.
Our beam splitter coatings for visible random polarized light allow a neutral splitting of light and laser beams. The semi-transparent optic features anti-reflective thin films on the back to avoid overlaid images or a phantom laser beam. The design of these components enables high performance and low light loss.
Our dielectric SIR has a heat-reflecting thin-film coating that is highly transparent for the visible spectrum and has a high reflectivity for infrared radiation up to about 1100 nm. We coat these thin films on heat-resistant borosilicate glass material, which allows a high thermal load and offers superb chemical stability. The deposition of customized infrared-reflecting coatings is possible on request.
The SIR-IR coating works similarly to that of our SIR. However, the visible transmission is not quite as high, as the design focus of this thin film coating is on a more broadband infrared energy-blocking range. We also use a borosilicate substrate for the SIR-IR.
Our SHD coatings feature a very efficient separation of visible light from infrared energy. The coating is all-dielectric and provides a tremendous visible reflection at an incidence angle of 45°. Simultaneously, it filters infrared light up to 2500 nm in transmission. So, the SHD thin films can also work as filters. The coating contains no metals and is first-surface coated. It is deposited on borosilicate glass materials with superb chemical durability.
Note: Manufacturing optics with custom dimensions according to your specifications based on vacuum vapor deposition, evaporation, or sputter coating technology is our daily business. The optical thin-film coatings listed above can be processed rapidly. Our advanced manufacturing capabilities enable a typical lead time of only 1–2 weeks for any optical component based on our standard thin films, even in large quantities. Moreover, we can process orders even faster! You can use our unique 48-hour express service, which is feasible for most thin film-coated materials. Of course, the possible delivery time depends on the part's complexity, required precision, material, the optics' shape, the necessary machining steps, and the technology needed to process it. With our quotation, you always get reliable information on the delivery time.
We offer advanced custom vacuum thin-film deposition and sputtering coating services and also provide precision ion-beam deposition technologies for high-performance thin-film systems based on almost any glass substrate material. Furthermore, we can control the transmissivity, cut-on, and cut-off points, as well as the reflection, of nearly any optical thin-film coating for wavelengths up to 2500 nm within certain physical and process limits. If you are searching for an optical thin film coating for your application that you cannot find here or need engineering support, please request a quote for your customized coating.
