Small and Thin Type of Gratings
- 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 angle is formed by an ion-beam etching technology , which easily makes blazed holographic gratings with various angles (blaze wavelengths).
- High groove density and high resolution gratings can be manufactured easily and at competitive price.
- Small and thin type of diffraction grating is suitable for spectrometer as optics.
