Optical Thin-Film Coatings

Our standard coatings

Here you will find a summary of our standard optical coatings. The manufacturing of these thin-film coatings takes place at regular intervals, to guarantee best availability of these materials even for parts with custom dimensions. Please succeed to the links below to view the data-sheets of the respective standard optical thin-film coated products:

 

Transparent Optical Coatings

 

ITO-Coatings on Glass

CEC-Series

We produce a variety of electrically conductive and transparent indium tin oxide thin-film coatings, which are applied to various high-quality glass types. Numerous exotic ITO-coated substrates, for example alkali-free glass, thin glass or quartz glass are constantly fabricated and always available.

 

Broadband Anti-Reflection Coatings

ARC-Series (VIS)

Our ARC coatings are efficient, optical, multi-layer antireflection thin film coatings that drastically reduce reflections from glass surfaces and suppress double images. They offer a significantly increased light transmission compared to uncoated glass. The coatings are based on selected high quality glass substrate materials. They can also be coated on customer's optics.

 

Optical Front Surface Mirrors

 

Enhanced Aluminium-Front Surface Mirror

SEA-VIS Series (VIS)

The SEA-VIS mirror has an aluminum metal coating with dielectric overcoatings, which are optimized for an increased reflectivity in the visible area. The coating is deposited on selected float glass substrate-materials. The mirror is economically priced and offers a good optical quality. The optical mirror can also be used for laser applications at low to medium laser beam energy.

 

Enhanced Aluminium Front Surface Mirror

SEA-NIR Series (NIR)

Our SEA-NIR 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 near infrared wavelengths.

 

Protected Aluminium Front Surface Mirror

SEA-UV Series (UV-VIS-IR)

The SEA-UV aluminum mirrors are protected by a very thin SiO2-layer coated on top of the aluminum layer. This ensures a high ultraviolet reflection and, at the same time, a very broadband reflectivity up into the IR range.

 

Silver-Metal Front Surface Mirror

SHP-Series

The SHP is a technical, silver metal coated optical mirror with a very powerful reflection for polarized and unpolarized light and laser radiation in the visible wavelength range.

 

Dielectric High Reflection Front Surface Mirror

SHR-Series (VIS)

The SHR is an optical front surface mirror with very high reflectivity in the visible, based on a purely dielectric thin film layer system. It is suitable for all applications requiring a very high reflection at an angle of incidence of 45°. The mirror can also be used for specific laser applications.

 

Dielectric High Reflection Front Surface Mirror for polarized light

SHP-D Series

The dielectric SHP-D front surface mirror has been designed for very high reflection for both, S & P polarized and unpolarized light for visible wavelengths and over a wide range of angles of incidence.

 

Dielectric Beamsplitters

DST-Series

Our beamsplitters for visible, random polarized light allow a largely neutral splitting of light and laser beams. The semi-transparent mirrors feature an anti-reflective coating on the back to avoid overlaid images and phantom laser beams.

 

 

Optical Coatings for Lighting Applications

 

Heat Reflecting Hot Mirrors

SIR-Series

Our dielectric coated SIR materials are highly transparent for visible light and strongly eflective for infrared radiation up to approx. 1100 nm. These thin-film coatings are coated on a temperature resistant borosilicate glass substrate.

 

Heat Reflection Filters

SIR-IR Series

The SIR-IR coating works in principle similar to that of our SIR hot mirror. However, the visible transmission is not as high and the design focus of this coating is on a more broadband infrared energy blocking range.

 

Dielectric Cold Mirrors

SHD-Series (VIS)

Our SHD front surface mirror materials allows a very efficient separation of usable light and heat. The dielectric cold mirror coating provides a very high, visible reflection with simultaneous infrared transmittance up to 2500 nm at an angle of incidence of 45° . The SHD is coated on heat resistant borosilicate glass materials.

 

 

Note: The manufacturing of optics with custom dimensions according to your specifications, based on the optical 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 be 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 additional required machining steps required to process it. With our quotation, you always get a reliable information on the delivery time.
