Having roots in the field of fundamental research, attocube offers a profound understanding of material characteristics and applied technologies not only in ambient, but also in extreme conditions. With the core competence in converting complex scientific devices into user-friendly industry products, attocube collaborated with today’s technological pioneers and developed the first commercial fiber based interferometer on the market.
The modular design makes cutting-edge measurement performance of interferometry accessible for various applications, even in extreme environments, and allows flexible integration into space confined machines and setups.
It is our goal to find the perfect solution for your needs, no matter how complex the challenge may be. Despite the versatility enabled by the combination of different standard components, some complex set-ups require services or products that are individually tailored to a specific application or environmental condition.
Whether you need test measurements, modification of optical components, or consulting on sensor head integration, attocube is your trusted partner for nano precise measurements. Contact us with your request and we will team up to solve your challenge.
Find the fitting sensor head:
Multiple sensor head types and individually customized focal lengths open broad application fields for interferometric measurement tasks. However it can be challenging to understand and derive the resulting key performance criteria for a specific setup.
Therefore, the shown diagrams provide a detailed overview of dependency between target type, focus length and measurement performance for attocube’s sensor heads.

Sensor Heads Overview – High Reflective Targets
measurement performance of selected customized sensor heads
Each line represents one specific sensor head and shows the achievable working distance, working range and corresponding angular tolerance for high reflective targets (e.g. mirrors). The focal length can be freely chosen by the customer to also cover areas in between the shown sensor heads. Please note that the exact values can change in dependence of the specific measurement setup. For a filtered selection, please click on the relevant sensor head type on the left.
Sensor Heads Overview – Low Reflective Targets
measurement performance of selected customized sensor heads
Each line represents one specific sensor head and shows the achievable working distance, working range and corresponding angular tolerance on low reflective targets (e.g. glass). The focal length can be freely chosen by the customer to also cover areas in between the shown sensor heads. Please note that the exact values can change in dependence of the specific measurement set-up. For a filtered selection, please click on the relevant sensor head type on the left.
Components adjusted for your measurement task:
Types of Optics
various optics for different sensor head geometries
Some measurement tasks require specific optics characteristics: for machine calibrations the measurement target can be freely chosen, such as e.g. a retroreflector. Yet, distances of several meters are essential. Material scientists however want to measure directly on various surfaces, but only in millimeter ranges.
The beam shape is the key to find a suitable solution for such diverse requirements. To ensure easy integration into your set-up, attocube offers suitable types of optics for different sensor head geometries.
Choices involve:
- focused or collimated
- filter options
- single or dual-pass
collimated and focused laser beams
dual-pass for increased angular tolerance
Focal Length
multiple combinations of working distances & angular tolerances
Focused sensor heads are the preferred choice when you have multiple measurement applications, require small laser spot sizes, need high angular tolerances, or need to measure directly on your material surfaces.
The focus length is crucial in order to achieve the best performance with your setup. attocube offers multiple focus lengths for every sensor head, allowing the best performance over a broad measurement range. Always focused on your application.
Choices involve:
- up to +-10° angular tolerance on various surfaces
- working distances up to 250 mm
flexible selection of focus lengths
Mounting
pre-aligned solutions & mounts for extreme environments
Enabling stable and user friendly mounting in extreme environmental conditions or space confined set-ups can be a challenging task. To facilitate the integration and start-up of the interferometer, attocube offers mounting solutions tailored to your application.
Adaptions range from individual sensor head modifications to pre-aligned multi-axis-solutions or traditional optical mounts.
Choices involve:
- pre-aligned and multi-axis solutions
- beam steering (e.g. 90° sensor heads)
- miniaturized mounts for extreme environments
pre-aligned multi axis solutions
optical mounts for extreme environments
Fibers and Feedthroughs
broad selection of fiber lengths, materials & feedthrough connections
The fiber-based design of the IDS3010 interferometer offers maximum flexibility during integration and operation, even when using its standard components.
We offer a broad selection of customizable optical fibers and vacuum feedthroughs to enable straight-forward integration, even for remote setup locations or inside vacuum chambers. We are happy to guide you to the best solution for your application.
Choices involve:

- feedthrough diameter and number of channels
different fiber jacket materials
various fiber types and diameters
different feedthrough diameters
different feedthrough types
up to 12 optical channels
Controller Modifications
application tailored firmware & electronics performance
Every detail is crucial, especially for demanding nano-scale applications that require extreme working distances, multiple encapsulated chambers, or ultra-low temperatures.
By tailoring the interferometer internal optics, electronics, and software, we can address nearly every challenge. Regardless of how complex your requirements are, you can team up with our engineers to find solutions.
Choices involve:
- ultra long ranges (up to 30 m)

Mirrors and Retroreflectors
measurement targets in various shapes & sizes, suitable for extreme environments
Applications aiming for larger working distances benefit from high-quality reflective targets, which usually are attached directly at the point of interest. As the measurement target is the core of the setup, the correct choice is imperative for successful measurements.
While retroreflectors offer high angular tolerances for movements up to several meters, mirrors allow larger lateral motions. To find the highest stability or flexibility for your application, we offer measurement targets in different shapes, materials, and sizes.
Choices involve:
- mirrors up to 400 mm length
- retroreflector materials and mounting
- mirror adapters for xy nanopositioning
