Spectrum Scientific, Inc.

Spectrum Scientific, Inc (SSI) has been manufacturing high volume flat, aspheric and freeform reflective optics and holographic diffraction gratings since 2004. We primarily use the optical replication process in our manufacturing allowing us to supply high fidelity, high specification precision optics at a fraction of the traditional cost of volume manufacturing. One of our key capabilities is the manufacture of freeform optics, off-axis paraboloids and ellipsoid mirrors with surface figures down to λ/10 or better. We also manufacture plane, concave and convex holographic diffraction gratings, which can be supplied as blazed gratings using our proprietary blazing technique, which not only offers high efficiency in the UV, but lower stray light than conventional ion etched gratings. Our high precision replicated optics, include spherical and aspheric mirrors (on or off-axis parabolic mirrors, elliptical mirrors, toroidal mirrors and cylinders) as well as retroreflectors, nanostructures, hybrid optics and complex optics. In addition to components, Spectrum Scientific offers a comprehensive design and manufacturing service, supplying custom designed UV spectrograph modules for OEM customers.
