Ibsen offers a line of spectrometer gratings spanning from UV bandwidths over VIS to NIR bandwidths, and also offers custom design of gratings for your OEM application. Production utilizes proprietary, cost-effective Holostepper technology, allowing the manufacturing of holographic, 100% fused silica MasterPieces at prices previously only possible for replicas.

Features and benefits

  • Holographic stepper patterning technology combines the highest quality of holography with the reproducibility and cost level of replicated gratings.
  • 100% Fused silica gratings provide unbeatable temperature stability, environmental tolerance and power damage threshold - including UV
  • Grating resolutions up to 5000 l/mm
  • High diffraction efficiency with high dispersion
  • Low polarization dependence (PDL) over broad spectral range
  • 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 Ibsen's extensive 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 ensures that agreed upon specifications are fullfilled.
