In the following, please find a summary of our standard thin-film coatings. We regularly do the vacuum vapor and ion-beam deposition of the listed thin films to guarantee the best availability, even for parts at custom dimensions. Please use the links below to view the datasheets of our standard thin-film coated materials:
We produce and process electrically conductive and transparent indium tin oxide thin films applied to various high-quality substrates by sputter deposition. This sputtering process provides an excellent micro-roughness of the ITO films on a level other deposition processes can't offer. Numerous exotic ITO-coated substrate materials, such as alkali-free glasses, thin glasses, or quartz glasses, are regularly fabricated and available. Customized sputtering of ITO coatings with a surface resistivity between 5 Ω/square and 1 kΩ/square is possible for production quantities on request.
Our ARC coating is an efficient multi-layer antireflection thin film coating that drastically reduces reflections and suppresses double images. The materials offer significantly increased transmittance and much lower energy loss than uncoated glasses. We deposit the ARC-layer systems on selected quality substrate materials. A deposition on materials provided by the customer is available for sufficiently large production quantities.
A high transmission characterizes our ARC-O antireflection coatings. They feature an additional oleophobic coating on the operator side. The grease, liquid, and dirt-repellent coatings reduce fingerprints on the anti-reflective coating to a minimum.
The SEA-VIS mirror has an aluminum metal thin film coating with dielectric over-coatings, which we optimized for an increased reflectivity in the visible area. The first surface coating is vacuum deposited on selected float glass substrate materials. The SEA-VIS is economically priced and offers excellent optical quality and mechanical stability, and can also be used for laser applications to deflect 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 on top of the metallic layer. This quartz coating ensures superb ultraviolet reflection, and at the same time, a broadband reflectivity up into the IR range.
The SHP has a silver metal coating with very 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 a purely dielectric thin film layer system. It is suitable for any application at an angle of incidence of 45° and unpolarized light. The SHR thin films can also be used for specific laser applications and can withstand a high thermal load.
We designed the thin film coatings of our dielectric SHP-D front surface mirrors for excellent reflection of S & P polarized and unpolarized light for visible wavelengths and a wide range of incidence angles. We achieve the outstanding performance of the SHP-D coating is by deposition of a large number of 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 loss of light.
Our dielectric SIR heat-reflecting thin-film coating is highly transparent for the visible spectrum and strongly reflects infrared radiation up to approx. 1100 nm. We coat these thin films on heat-resistant and borosilicate glass materials that allow a high thermal load and superb chemical stability. The deposition of customized infrared reflecting coatings is possible on request.
The SIR-IR coating works similar to that of our SIR. However, the visible transmission is not quite as good, and the design focus of this thin film coating is on a more broadband infrared energy blocking range. We also use a borosilicate substrate that offers excellent chemical resistance.
Our SHD-coatings allow a very efficient separation of usable light and heat. Its dielectric coating layers provide a tremendous visible reflection at an incidence angle of 45° and simultaneously filter infrared light up to 2500 nm by transmission. So the SHD thin films can also work as filters. The coating contains no metals and is first-surface coated, and is deposited on borosilicate glass materials with superb chemical durability.
Note: The manufacturing of optics with custom dimensions according to your specifications based on vacuum vapor deposition, evaporation, or sputter coating technology is our daily business. The thin-film coatings listed above can usually be processed very quickly. 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 take advantage of our unique 48h-Express Service, which is feasible for most thin-film coated materials. Of course, the exact possible delivery time depends on the part's complexity, required precision, the material, the optics' shape, machining steps necessary, and the technology needed to process it. With our quotation, you always get reliable information on the delivery time.
If you search for a thin film coating for your application that you cannot find here or need engineering support, please request a quote for your customized coating. We offer advanced custom vacuum thin-film deposition and sputtering coating services. We also provide precision ion-beam deposition technologies for different high-performance thin-film systems based on almost any substrate glasses. We can control transmissivity, cut-on, cut-off points, and the reflection of nearly any optical thin-film coating for wavelengths up to 2500 nm within certain physical and process limits.
