Thin Film Coatings

Standard transparent and reflective thin films

See here for customized coatings

In the following you will find a summary of our standard thin film coatings. The vacuum deposition of these thin films takes place at regular intervals to guarantee best availability even for parts at custom dimensions. Please use the links below to view the data-sheets of our respective standard thin film coated materials:


Transparent Coatings


ITO-coated glasses CEC-Series

We produce and process a variety of electrically conductive and transparent indium tin oxide thin film coated materials which are applied to various high-quality substrates by sputtering processes. Numerous exotic ITO-coated substrate materials, for example alkali-free glasses, thin glasses, or quartz glasses are constantly fabricated and available. Custom sputtering of ITO-coatings with a surface resistivity between 5 Ohms / sq. and 1 kOhm / sq. are possibly at production quantities on request.


Broadband Anti-Reflection Coatings ARC-Series (VIS)

Our ARC coating is an efficient multi-layer antireflection thin film coating that drastically reduces reflections and suppresses double images. The material offers a significantly increased optical transmission and much lower energy loss than uncoated glasses. The ARC-coatings are based on selected high quality substrate materials. A coating deposition of customer's supplied optics is also possible at production quantities.



Reflective Coatings


Enhanced Aluminum SEA-VIS Series (VIS)

The SEA-VIS mirror has an aluminum metal thin film coating with dielectric over-coatings which is optimized for an increased reflectivity in the visible area. The front surface coating is deposited on selected float glass substrate materials. The SEA-VIS is economically priced and offers a good optical quality and mechanical stability. It can also be used in laser systems to deflect laser beams in applications at low to medium laser beam energy.


Enhanced Aluminum SEA-NIR Series (NIR)

Our SEA-NIR front surface mirror has the same basic design and substrate as the SEA-VIS series but the dielectric films on top of the metal thin film coating have been optimized for applications in the near infrared wavelengths.


Protected Aluminum SEA-UV Series (UV-VIS-IR)

The SEA-UV aluminum metal front surface mirror is protected by a very thin SiO2-layer coated on top of the aluminum layer. This ensures a high ultraviolet reflectivity and at the same time a very broadband reflectivity up into the IR range.


Silver-Metal SHP Series (VIS-IR)

The SHP coating is a silver metal coated first surface mirror with a very powerful reflectivity for polarized and unpolarized light and laser radiation in the visible wavelength range.


Dielectric High Reflection SHR-Series (VIS)

The SHR is a metal free high performance mirror with very high reflectivity in the visible based on a purely dielectric thin film layer system. It is suitable for any application requiring a very high reflection at an angle of incidence of 45°. The SHR materials can also be used for specific laser applications.


Dielectric High Reflection for polarized light SHP-D Series (VIS)

The thin film coatings of our dielectric SHP-D front surface mirrors have been designed for very high reflectivity for S & P polarized and unpolarized light for visible wavelengths and over a wide range of angles of incidence. The outstanding performance of the SHP-D mirrors is achieved by deposition of a large number of optical thin film layers.


Dielectric Beam splitters DST Series (VIS)

Our beam splitter coatings for visible random polarized light allow a largely 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 enable a high performance and low loss of light.



Coatings for Lighting Applications


Heat Reflecting Hot Mirror SIR Series (VIS/IR)

Our dielectric coated SIR thin film coating material is highly transparent for the visible spectrum and strongly reflective for infrared radiation up to approx. 1100 nm. These thin films are coated on a heat resistant and borosilicate glasses that offer a high chemical stability. The deposition of customized hot mirror coatings is possible on request.


Heat Reflection Filters SIR-IR Series (VIS/IR)

The SIR-IR coating works in principle similar to that of our SIR. However, the visible transmission is not quite as high and the design focus of this thin film coating is on a more broadband infrared energy blocking range. It is also based on a borosilicate substrate that offers a high chemical resistance.


Dielectric Cold Mirror SHD Series (VIS/IR)

Our SHD-coatings allow a very efficient separation of usable light and heat. Its dielectric coating layers provide a very high visible reflection at an angle of incidence of 45° and simultaneously filter infrared light up to 2500 nm by transmission. So the SHD thin films can also be used as filters. The coating is first surface coated, metal free, and it is coated on heat resistant borosilicate substrate materials.


Note: The manufacturing of optics with custom dimensions according to your specifications based on the thin films listed above usually can be done within extraordinarily short delivery times. For optics based on any of our standard thin film coatings even at large quantities our advanced manufacturing-capabilities enable a typical lead time of only 1-2 weeks. And we can process orders even faster! You can take advantage of our unique 48h-Express Service which is feasible for most of these thin film coated materials. Of course the exact possible delivery time is depending on the complexity of the part, required precision, the material, the shape of the optics, and on additionally machining steps and technology required to process it. With our quotation you always get a reliable information on the delivery time.
