Ion Etched Diffraction Gratings

Aberration-corrected Toroidal Gratings Series
from Shimadzu Corporation

The toroidal diffraction gratings are made by aspheric blanks where each curvature of orthogonal two axes (meridional and sagittal) is different. The toroidal diffraction gratings are formed on toroidal (aspheric) blanks that can correct astigmatisms. [See More]

  • Grating Type: Holographic
  • Groove Frequency: 550
  • Grating Design: Toroidal Reflection
  • Blaze Wavelength: 340 to 400

Laminar Gratings for Soft X-ray Region
from Shimadzu Corporation

Applying holographic exposure method and ion-beam etching technology, Shimadzu has developed laminar gratings for spectroscopy in a range from the vacuum ultraviolet region to the soft X-ray region. These gratings have grooves with a rectangular profile, which are directly etched into blanks made... [See More]

Plane Blazed Holographic Gratings Series
from Shimadzu Corporation

The grating grooves are formed by a holographic exposure method where the two-laser-beam-interference technology is applied. This holographic method lowers groove's periodical error commonly found in mechanically ruled gratings and ensures that the low stray light gratings can be produced. Blaze... [See More]
