Our UV Advantage

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

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 typical efficiencies of 80% or greater.
