Spectrum Scientific, Inc (SSI) manufactures high volume flat, aspheric, and freeform reflective mirrors and holographic diffraction gratings using an optical replication process allowing us to supply high fidelity, high precision optics at a lower cost compared to traditional volume manufacturing.

Our products include diffraction gratings, aspheric mirrors (on or off-axis parabolic mirrors, elliptical mirrors, toroidal mirrors and cylinders), freeform mirrors as well as monolithic hollow retroreflectors, hybrid optics and complex optics.

Spectrum Scientific Gratings Holographic Diffraction Gratings
Our holographic diffraction gratings are holographically 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:
  • Blazed Holographic Diffraction Gratings
  • Plane, Convex and Concave
  • Pulse Compression Gratings
  • Telecom Gratings
  • Space Qualified Gratings 
Aspheric & Freeform Mirrors
Spectrum Scientific MirrorsOne of our key capabilities is the manufacture of freeform mirrors, off-axis parabolic mirrors, and ellipsoidal mirrors with surface figures down to λ/10 PV or better.
  • Spherical and Aspheric Mirrors
  • On or Off-Axis Parabolic Mirrors
  • Elliptical Mirrors
  • Toroidal & Cylindrical Mirrors
  • Freeform Mirrors
  • Space Qualified Mirrors 
Hollow Retroreflectors
Spectrum Scientific RetroreflectorsOur range of hollow retroreflectors are manufactured from solid aluminum giving a rugged, monolithic construction which is insensitive to vibration and movement making them ideal for use in laser based measurements, FTIR spectrometers and interferometers.
  • <2 arcsec Return Beam Accuracy
  • Gold and Aluminum Coatings
  • Custom Dimensions Available
  • Custom Mounting Features
  • One-piece Monolithic Design 
Miniature UV Spectrometers
In addition to components, Spectrum Scientific offers a comprehensive design and manufacturing service, supplying custom designed spectrograph modules for OEM customers as well as a range of ultra-low stray light UV spectrographs.

From design services to rapid prototyping, and OEM production, Spectrum Scientific can meet all of our customers’ replicated optics needs. We utilize six sigma and lean manufacturing principles in our continuous effort to strive for excellence in all we do.
