Lithographic or holographic stepper patterning technology combines the highest quality of patterning with the reproducibility and cost level of replicated gratings

100% Fused silica gratings provide unbeatable temperature stability, environmental tolerance and power damage threshold – also in the UV

Grating resolutions up to ~3000 l/mm

High diffraction efficiency with high dispersion

Low polarization dependence (PDL) over broad spectral ranges

Combined wavelength dispersion and folding elements

Multiple prototyping, small and high volume production technologies

Class 10 cleanroom production ensures low noise and high cleanliness – as well as a controlled environment for our metrology capabilities

Extensive grating metrology including proprietary period measurement systems, a versatile diffraction efficiency measurement system, a high resolution defect inspection system as well as AFM/SEM ensuring that agreed upon specifications are fulfilled
