Customized lenses

Customized Lenses

If a standard lens from our portfolio is not suitable for your challenges, we will manufacture customized solutions for you. In industrial optics, there are often requirements that cannot be met with standard lenses. In such cases there are two options: The modification of an existing lens or the development of a special lens. The possibilities are virtually unlimited. We understand that every project is unique and we will do our best to provide you with the perfect solution. Our focus on quality and innovation is evident in every industrial lens we modify. By working closely with our customers, we ensure that we can make your requirements a reality.

Lens modification

Modification involves adapting an existing lens to meet specific customer requirements, for example by optimising the working distance or applying a special coating to optimise the lens for a particular wavelength. Modification may also involve adjusting the housing format or mount of the lens to optimise it for a particular camera or application.

The advantage of modification is that it is often quicker and cheaper than developing a completely new lens. In addition, an existing lens can be used as a base, reducing development time.

Lens development

The development of a custom lens focuses on meeting specific requirements through innovative design. For example, a lens can be tailored to excel in unique scenarios such as special imaging conditions, particular focal lengths or application-specific needs.

The key benefit of embarking on a new development project is that the lens is meticulously optimized to meet the exact requirements of the customer. This optimization ensures that the resulting lens delivers unparalleled performance and uncompromised quality tailored to the specific application.


Possible lens modifcations




Ruggedized & Stabilized Lenses

Ruggedized lenses offer longer life and resistance to harsh environments, making them ideal for applications in aerospace, mining, oil and gas and other harsh environments. The rugged construction ensures that the lens will perform optimally even in the harshest conditions.

Stabilized lenses offer improved image quality by reducing vibration and movement. This makes them ideal for applications where a clear and stable image is required, such as medical imaging or 3D measurement.

Fixed aperture lens
Lenses with Fixed iris

For example, fixed aperture lenses tend to be simpler in construction and therefore more robust and reliable. In addition, they can often be offered at a lower price for the same optical performance. In situations where constant exposure is required, such as in many industrial applications, fixed aperture lenses are advantageous. Their fixed aperture size eliminates the need for frequent adjustments, ensuring reliable and stable performance in a variety of working conditions. This reliability is especially important in industries where precision and durability are paramount.

Optimization of Working distance

This optimization allows our customers to ensure that they get the best possible optical performance when viewing or recording objects at a specific distance.

Working distance optimization is particularly useful for applications such as industrial inspection, where objects often need to be viewed from a specific distance. By optimizing the lens to the correct working distance, our customers can ensure that they get sharp images that capture all the important details of the object.

Optimized working distance
Special wavelength
Lenses for Special Wavelengths

Lenses can be optimized for a specific wavelength range by using special materials and coatings that are best suited to that wavelength.  The design of the lens can also be adapted to the specific wavelength to ensure optimum performance. This optimization allows the lens to achieve higher resolution and contrast and provide more accurate measurements, which is important for many applications.

Wavelength tuning is particularly useful for applications such as spectroscopy or laser technology, where it is often necessary to work with specific wavelengths. By optimizing the lens to the correct wavelength, our customers can ensure they get sharp images and make accurate measurements.

Size and weight reduction of lenses

As a manufacturer of high quality lenses for a wide range of industrial applications, we know that the size and weight of a lens is an important factor for many customers. That's why we specialise in developing lenses that not only offer outstanding optical performance, but are also compact and lightweight.

By using the latest technologies and materials, we are able to produce lenses with significantly reduced size and weight without compromising optical performance. This allows our customers to make their systems lighter and more compact, resulting in greater mobility and flexibility in a variety of applications.

The compactness of the lenses also has the advantage that they can be used in applications where space is at a premium. 

Modification of housing

Add-on - Lenses with beamsplitter

A beamsplitter can be added to a lens. A beam splitter is an optical element that can split an incident beam into two beams. One part of the light is reflected and the other part is transmitted. This technology is used in many applications such as metrology, microscopy or optical data transmission.

By integrating a beamsplitter into the lens, the light can be split and directed in different directions. This can be particularly useful when the lens is used in combination with other optical components to manipulate or analyse the light. An example of this is the use of beamsplitters in stereomicroscopy, where two separate lenses are used to create a spatial representation of the object.


Methods of modifying a lens


Mechnical modification of lenses

Mechanical modification refers to the design of the lens and its mechanical properties. The aim is to design lenses that are reliable and durable. This includes, for example, the choice of materials, the design of the housing and the specification of dimensions and tolerances. Mechanical optimization is essential to ensure that the lens functions reliably even under difficult conditions such as vibration, shock or temperature changes.

Optical modification of lenses

Optical modification refers to the design of the lens and its optical properties. This involves designing the lens to deliver high image quality. This includes, for example, the selection of lenses, their arrangement, the determination of their radii of curvature and the choice of coatings. Optical optimisation is essential to ensure that the lens delivers sharp, high-contrast images and meets user requirements.
