Transmission gratings
Ibsen Fused Silica Transmission Gratings are the ideal choice for applications ranging from high power lasers to telecom devices to compact spectrometers.
Diffraction gratings are used either as beam splitting elements (e.g. Phase masks) or as dispersion elements for wavelength separation. Ibsen fused silica transmission gratings are the ideal grating choice for a wide range of applications:
Telecom devices such as Wavelength Selective Switches (WSS), Tunable Filters (TF) and Optical Channel Monitors (OCM)
High power laser applications such as pulse stretching / compression, spectral beam combining or beam-splitting
Compact spectrometers for absorption spectroscopy, fluorescence spectroscopy, Raman spectroscopy, OCT and color measurements
Advantages:
Ibsen’s fused silica grating technology was developed by Ibsen in the mid 90’s and has continuously evolved ever since. Ibsen’s gratings are characterized by being 100% dielectric, surface relief etched transmission gratings, and offer many advantages:
Environmentally stable as no coatings, polymers or epoxies are used
Low thermal expansion coefficient
Low temperature sensitivity
Highest energy / power damage threshold
Transmission gratings provide more flexibility in the optical design than reflection gratings – choice of beam path, multiple gratings
Ideal in cases where the input location must be spatially separated from the detector location
Combined wavelength dispersion and beam folding elements
Absence of complex absorption issues provides more homogenous DE values over the spectral band
Holographic or lithographic exposure, etched gratings
High diffraction efficiency combined with high dispersion
High tolerance to illumination angle of incidence
Low stray lightfused silica transmission gratings
