Highly Precise Adjustment of DUV Optics thanks to Patented Mounting Technology
Jenoptik developed a stress-free mounting technology for DUV optics as part of a project sponsored by Thüringer Aufbaubank (TAB). This technology holds optical elements without the need for an adhesive.
It is completely free of adhesives and uses stackable technology (stack-mounting). This reduces stress-induced birefringence and increases the stability of the optical components — the objective lenses perform even under the most demanding conditions.
The new concept means you can mount optical elements precisely: You can position them perpendicular to the optical axis at an accuracy of less than ten nanometers over a range of around 300 microns. This means you can adjust the optical elements in DUV optical systems very precisely and ensure they are well secured.
The Jenoptik technology funded by the Thüringer Aufbaubank as part of a project is used for optical material such as calcium fluoride and quartz glass and mounting materials such as stainless steel, aluminum and bronze.
Universal Wavefront Measurement System Guarantees Quality
With the wavefront measurement system, you can adjust and qualify the entire system quickly and accurately, saving you time and money. Jenoptik combines different measuring principles in one measuring system, which can be universally adapted — saving development time and costs.
