- Groove frequencies ranging from 600 to 2400 g/mm
- Spectral ranges: from 190 to 1750 nm
- Diffraction efficiency optimized for UV, or Vis, or NIR
- 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.
Fig. 2: Typical efficiency curves* for 530 13, 2400 l/mm, 190-700 nm
*These efficiency curves are absolute theoretical efficiencies, calculated using rigorous electromagnetic theory, taking into account the true groove profiles of manufactured gratings measured with an atomic force microscope (AFM).
