- Ibsen Phase masks have been manufactured in cleanroom environment for 10 years, today in class 10 state-of-the art facilities that we established in 2000.
- Phase masks are special transmission diffraction gratings - Ibsen's core technology. Besides being a market leader in Phase masks and Fused Silica Transmission Gratings, we manufacture gratings for our own I-MON and Spectrometer modules.
- The unbeatable period accuracy (+/- 0.01 nm) of our Phase masks has been utilized to provide the EU with Calibration Standards that are EU certified by 3 national European metrology labs (NPL, PTB and DFM).
- Holographically produced
- 100% Class 10 cleanroom production
- 0.01 nm period accuracy and uniformity
- Continuous, linear chirp is possible
- Tight diffraction efficiency control
- Extensive metrology (period, DE, defects)
- Clear, on-mask identification
- +1/-1 order Phase masks. Ibsen offers Phase masks for replicating Bragg grating structures into fibers (FBGs) and waveguides. Holographic production techniques yield Phase masks that are inherently free of stitching errors, and provide continuous, linear chirp as an option. Period accuracy and uniformity is better than 0.1 Angstrom, idea...
