In addition to our many standard thin film components, we produce custom optical thin film coatings to your exacting requirements. The following overview presents a summary about the most common types of coatings. We coat these optical coatings mainly on flat optical substrates but depending on the details it is also part of our capabilities to coat lenses and precision optics. Please follow one of the links to our coating inquiry form to conveniently enter the characteristics of your required customized coatings:
Optical coatings with mainly reflecting properties and high imaging quality. These can be based on all dielectric or metallic coatings, like aluminium, enhanced aluminium, silver, enhanced silver, gold, chrome, copper or platinum. The optical reflection, angles of incidence, polarization and most other characteristics can be adjusted according to custom requirements. In addition to our standard mirror coatings you can use our custom optics enquiry form to conveniently request a quotation for your customized mirror coating.
Optical coatings used for neutral splitting of light or laser radiation or for defined damping of a light source. Beamsplitters can either be based on dielectric or metallic coating systems. The splitting ratio can be adjusted to customer’s specification by modifying the thin film layers. The backside can be anti-reflection coated to minimize unwanted secondary reflections and to prevent energy loss. In addition to our stock beamsplitter coatings, you can use our custom optical thin films quotation form to conveniently get a quote for your customized beamsplitter.
Thin film coatings that minimize or eliminate unwanted reflections and ghost images or double laser beams which occur from uncoated glass surfaces. The optical design can be optimized for single wavelengths or for a wide wavelength range (broadband AR-coating) and extra low reflection. The usable transmitted light is often increased by the same amount the rest reflection is decreased. In addition to our off-the-shelf anti-reflection coatings you can use the coating inquiry form to conveniently get a quote for your customized anti-reflective coating design.
Dielectric optical coatings with a high reflection in the visible range and good transmittance in the infrared range. A cold mirror is mainly used to efficiently filter out heat or IR-radiation from a lamp or an optical system. The cut-on and cut-off wavelengths and the range of reflection can be shifted or modified according to customer‘s specific requirements. In addition to our standard cold mirrors you can use the coating enquiry form to conveniently get a price for your custom designed cold mirror optics.
Dielectric optical filters with high transmission in the visible and high reflection in the infrared are predominantly used to block heat or IR-radiation. These filter coatings can also be used as transparent reflectors in the infrared spectrum such as near infrared laser diodes (eye-tracking e.g.). The cut-off wavelength, optical transmission and reflection ranges of the filters can be customized. In addition to our standard hot mirrors you can use the coating request form to conveniently get a price quote for your custom hot mirror coating.
Electrically conductive coatings with good optical transmission in the visible and with a defined electrical sheet resistance. The sheet resistance and transmission depend on the film thickness and can both be customized. Sheet resistances can be in the range from 5 Ω/sq. up to 10 kΩ/sq. The backside can be anti-reflective coated to reduce secondary reflections. ITO-coatings with a low surface resistivity can be used as infrared reflecting optics. In addition to our standard ITO-coated materials you can use the coating enquiry form to conveniently get a quotation for your customized ITO-coated material.
We are not limited to the optical coating services and capabilities described before. In addition to the coatings listed, we can manufacture the following thin film coatings to customers specification:
