- Groove frequencies ranging from 120 to 1800 g/mm
- Spectral ranges: from 190 nm to 45 microns
- Diffraction efficiency optimized for UV, or Vis, or IIR
- Dimensions: from 25x 25 mm to 120 x140 mm
For customers in need of larger dimensions, HJY can record a custom-made holographic grating master specifically for replication.
