Aspherical optics for precision, flexibility and economy
This innovator in aspherical optics has developed different materials for every wavelength and focal length for greater precision, flexibility and economy. Based in Germany, asphericon has in 20 years evolved from a component manufacturer to a system designer and manufacturer.
Aspheric lenses deliver far better optical performance than standard spherical surfaces. asphericon’s digitised processes and in-house software has revolutionised aspheric lenses’ precision and quality while its user-friendly, modular range has made beam-shaping packages more accessible.
asphericon’s aspheric lenses, optics and systems bring visions to life in manufacturing, industrial technology, life sciences, aerospace and others relying on high-quality optics.
The company’s high-end manufacturing processes and applications mean asphericon routinely achieves unique levels of dimensional precision for components and for complete optical systems.
asphericon’s comprehensive portfolio runs from high-quality aspheric lenses, axicons and aspheric cylinders to mirrors and reflectors, spherical components and ultra-precision mounted optics.
Beam Tuning
Laser beam expansion
The world’s first aspheric lens for laser beam expansion opens new opportunities not possible with conventional laser beam expanders. An aspheric beam expansion lens corrects spherical aberrations and realises an afocal system for large input beam diameters and and can reduce system size by up to half. asphericon’s laser beam expander system covers a wide wavelength spectrum including design wavelengths of 355 to 1064 nm and works completely diffraction-limited, both as a single element and in cascades of additional coated elements, and up to 32x expansion.
Laser fibre coupling and collimation
The sophisticated optical design of asphericon’s adjustable fibre collimators/couplers enables simple fibre coupling, alignment of FC/PC patch fibres, and wavefront modification with minimal adjustments. Users can combine collimators with BeamTuning or other beam-shaping elements for any chosen output beam while maintaining a diffraction-limited wavefront. asphericon’s compact, adjustable fibre collimator/coupler perfectly aligns FC/PC patch fibres and require little effort to adjust wavelengths.
Beam shaping
Efficient top-hat beam shapers are optimised for all wavelengths 300-1600 nm and maximum results in all laser applications. These modular components allow straightforward transformation of Gaussian laser beams into various round and square top-hat profiles. The range has top-hat shapers for long-distance work and applications with smaller beam diameters at shorter distances.
