- Aberration-corrected Laminar-type Replica Diffraction Gratings for flat-field Polychromators in the range from Vacuum Ultra-Violet(VUV) to Soft X-ray Region. We offer a wide range of lineups for wavelengths from 0.6 nm to 200 nm.
- Less high order light due to laminar type grooves configuration, Low stray light by holographic manufacturing technology, and high resolution from aspherical waves exposure method .
- Easy to design spectrometers with array-type detectors.
- Suitable for monitoring EUV lights as well as for Emission Spectroscopy
Applications
- Spectroscopy in the VUV/XUV(EUV)/soft X-ray region.
- High-harmonic generation（HHG）
