SSI Blazed vs. Ion Etch

Comparison between SSI blazing technique and ion-etched blazing

 A holographic diffraction grating can be blazed using a number of different methods. The proprietary technique used by Spectrum Scientific creates a blazed grating that demonstrates considerably less stray light with equivalent or better efficiency when compared to an ion-etched blazed grating.
