Founded in 2004, Spectrum Scientific Inc. (SSI) is a leading manufacturer of high-volume, high-precision reflective optics and holographic diffraction gratings. Specializing in cost-effective optical replication technology, our capabilities include:

• Blazed holographic gratings with ultra-low stray light and high UV efficiency, out-performing conventional ion-etched alternatives, including aberration-corrected flat-field gratings and concave gratings optimized for spectroscopy and imaging
• Aspheric and freeform mirrors in glass, metal, Invar, or silicon carbide
• Monolithic Hollow Retroreflectors
• Specialist DUV/VUV coatings

We excel in replicating complex optical geometries, including off-axis parabolas, ellipsoids, and freeform surfaces, achieving surface figures down to λ/10 and angstrom-level surface roughness. Our optical gratings are available as ruled and sinusoidal or blazed holographics in plane, concave, and convex formats, and our proprietary blazing method ensures superior performance for demanding UV applications.

SSI operates an ISO 9001:2015 certified, RoHS-compliant, and space-qualified facility with a silicone-free cleanroom environment.

Our proprietary optical replication process enables the production of complex optical components with exceptional precision and repeatability – making SSI an ideal partner for analytical instrumentation, life sciences, aerospace, metrology, and telecom applications and we are trusted in critical applications including spaceborne instrumentation used in notable missions such as NASA’s Orbiting Carbon Observatory (OCO) and Ozone Mapping Profiler Suite (OMPS).

Our optical coating technology includes a range of very high reflectivity DUV and VUV coatings, offering industry leading performance for demanding applications in spectroscopy as well as in the study of electronic circuits, in high resolution microscopy and selective molecular imaging

In addition to components, we offer bespoke optical assemblies for OEM integration – combining advanced optical design, engineering, and manufacturing under one roof.
