Optical applications for the automotive sector
In addition to progressive electrification, the mobility of the future means above all the use of artificial intelligence to develop autonomous vehicles and increasingly networked communication. But topics such as safety and new driving experiences are also pushing the pace of innovation in the market. Photonic systems support the realization of these task complexes, e.g. within the areas of autonomous driving or illumination and lighting technology. The development of more compact optical systems, without losses on image quality and resistance to external influences, is also at the center of considerations.

- Freeform optics for miniaturized systems
- Optical components for challenging LIDAR solutions
- Compact and effective optical designs
Materials and geometries for automotive applications
The selection of materials for optical components and systems is the first important step for innovative applications. In addition to very high image quality, optics should also be highly resistant to external environmental influences. Especially when processing IR materials, which can be used e.g. within night driving systems, outstanding surface shape tolerances must be guaranteed. asphericon produces optics for the automotive sector e.g. from the following materials:
- Glass
- Silica
- IR-materials and
- Metals
- Other materials on request
Types and shapes of optics can be as diverse as the materials used. asphericon manufactures, measures, and characterizes aspheric lenses, spheres and diffractive elements as well as freeform optics for automotive applications. You can also obtain high-performance optics from us with edge coating and/or laser marking as well as with bevels, bores or steps.
A final processing step can be carried out by coating. The selection of the coating process is customer- and project-specific, whereby almost all spectra (190 - 5100 nm) can be achieved on a wide variety of materials. Our optical coating portfolio includes wavelength-specific, anti-reflection, mirror, filter, IR and metal coatings.
Individual optical designs and most precise manufacturing processes
For the realization of various automotive applications complex opto-electronic systems are required, which consist of optics, sensors, and electronic components. The size of the installation space is often limited, which places special demands on the design of the single elements. This is particularly true for optical components, whose design increasingly follows the trend towards miniaturization. Based on specific requirements and individual customer needs, asphericon provides support for sophisticated optical designs. All individual designs are implemented on state-of-the-art CNC-based grinding and polishing machines. Best manufacturing results can also be achieved by monocrystalline machining. asphericon’s fully automatically controlled machining processes enable the production of optics with smallest surface shape deviations.
Specific areas of application
There are several possible applications for optical components in the automotive sector. Driver assistance systems (e.g. distance measurement, parking assistant) benefit from special camera systems, sensors, and software units. In camera systems, for example, aspheric lenses are used to achieve the best possible imaging results. In the future, the increased use of freeform optics could further improve system performance and advance miniaturization.
Night driving systems are a special type of driving assistance systems. Using a thermal imaging camera, infrared signals can be visualized on a display located in the cockpit, thus making an important contribution to passenger safety. The basis for thermal imaging cameras are high-quality optical components (e.g. spherical and aspheric lenses) in combination with special coatings.
LIDAR (Light Detection and Ranging) systems are used in the automotive sector to generate three-dimensional images of the environment or to determine distances and speeds. Based on optical components, this technology is intended to enable autonomous driving.
Extensive environmental testing for long-life lenses and systems
Optical components have to meet high requirements: Robust and durable, they must withstand daily use reliably. High temperature differences, humidity or contamination must not negatively influence the imaging properties and performance of spheres, aspheres or optical systems. The solution are optical components that pass extensive environmental tests. These include, for example, adhesion, humidity and temperature tests. asphericon carries out such tests in-house. Our products impress through constant best performance and easy handling in daily use. As a reliable partner, optics from asphericon can complement microscopes, laser and camera systems, as well as many other optical devices in the field of security applications.
The same applies to optical coatings. You have the possibility to have existing optics coated afterwards or to seal new optical elements. Our optical refinements effectively help to minimize reflections in beam paths or to allow certain wavelengths to pass through.
