SSI’s UV Advantage

Spectrum Scientific is uniquely qualified to blaze in the UV. Our proprietary UV blazing technique provides superior quality and our replication process allows for high fidelity and high quantities but low costs. Our replicated UV gratings have been tested down to 120nm and proven to maintain their superior specifications. 

Efficiency comparison vs ion etched

In addition Spectrum Scientific is one of the few companies in the world with the capacity to blaze UV holographic concave gratings with a profile that varies across the grating surface. This greatly increases the efficiency across the full image plane and allows for a typical efficiencies of 80% or greater.
