The HELIOS sputter coater from Bühler is designed to meet the highest demands for thin-film coatings. Use it for laser line, steep-edge and notch filters, laser and chirped mirrors, polarizers, beam splitters, bio and ADAS sensors or consumer electronics.
State of the art PARMS (Plasma-Assisted Reactive Magnetron-Sputtering) technology allows the deposition of dielectric coatings from metal targets with high- and low-refractive indices by combining mid-frequency (MF) and radio-frequency (RF) sputter technologies via two magnetrons. This allows you to enjoy high productivity for top grade products, with the ultimate precision at atomic scale.
Our renowned in-situ optical monitoring system LEYBOLD OPTICS OMS 5100 ensures the precise termination of the deposition process of each layer. For larger layer stacks and when using the automated loading system, test glasses can be exchanged without the vacuum being broken. This means HELIOS tools allow for long hours of unattended operation without compromising the quality of your product.
You can quickly transfer optical designs into and between production tools. The coaters perfectly match production in a wide range of filter designs. This helps to rapidly prototype new products and cut time-to-market.
Sputtering and co-sputtering
With high material and target flexibility, filters based on high and low index sputtering materials can be produced and improve the flexibility of the tools. By simultaneously using two separate sputter stations, the HELIOS can successfully tune the index to a desired intermediate value.
Customizable
From different substrate sizes and types to different types of handling systems and an extensive list of sputter target materials, the possibilities are endless with the HELIOS. Customize your HELIOS vacuum coater to match what you need for your product, process, and production.
Color and near infrared wide bandpass and cut filters for applications such as ambient light sensors or CMOS image sensors. Narrow bandpass filters matching the wavelength of the dot projector enables applications in facial recognition.
From antireflective and high reflectivity coatings to complex filter designs built directly on wafers.
As smaller sensors are implemented in wearables, high precision coatings and waveguides are being built right onto smaller elements.
NIR bandpass filters and AR coatings for sensors to block ambient and external light from disturbing the sensing system.
Multicolored bandpass filters to add chemical or surface structure information to digital images.
Edge filters such as short or long pass filters help selecting the spectral range of photospectrometers for outstandingly precise measurements and calibration purposes. Band pass filters increase the selectivity of sensor applications and narrow down the wavelength range of a broad band light source.
UV-IR cut filters protect sensitive lens optics inside a camera lens and enhance the contrast in the visual wavelength range by canceling the high energy UV light as well as IR light pollution. Sunlight and moonlight filters enhance the contrast for observations made with astronomical telescopes.
Dielectric mirrors, polarizers and beam splitters are used in interferometers or optical benches to manipulate the path of a light beam for precise measurement of optical properties of a specimen. Mirror optics and semi-transparent mirrors keep geometrical measurement devices small enough to be handled easily.
Multi-notch filters enhance the quality of microscopic images created by fluorescence microscopy, allow for quantification of cell components while protecting the human eye from harmful UV light. Multi-band-passes and line filters help in rapid quantification of expression markers in medical analysis technology, including very the famous RT-PCR method.
Extremely narrow band pass enable telecommunication signals to be multiplexed and demultiplexed for complex information transmission in large networks via fiber optics.
Bühler’s services and training are designed to keep you up to date on products and technologies, giving you the confidence and experience you need.
