Ibsen fused silica transmission gratings enable high resolution, high efficiency gratings that are ideal for compact spectrometers
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 using our stepper lithography or proprietary, cost-effective Holostepper technology, allows manufacture of holographic, 100% fused silica Master gratings at prices previously only possible for replicas.
Lithographic or holographic stepper patterning technology combines the highest quality of patterning with the reproducibility and cost level of replicated gratings
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
In addition to OEM grating supply, Ibsen offers a full line of standard spectrometer gratings which are available from stock.
The full Ibsen grating portfolio comprises 4 different grating types that may be suitable for various spectrometry applications:
Extremely high efficiency (any polarization) gratings
(polarization independent gratings)
Extremely high efficiency (single polarization) gratings
(narrowband single polarization gratings)
Very high efficiency spectrometer gratings
(narrowband spectrometer gratings)
High efficiency spectrometer gratings
(full octave spectrometer gratings).
