What Spectrogon does

Spectrogon AB is a privately-held Swedish photonics component manufacturer headquartered in Täby (with two production sites in Täby/Arninge totaling 3,600 square meters), tracing its origin to research at the Royal Institute of Technology (KTH) and AGA AB and operating as an independent company since June 28, 1991. The company develops and manufactures optical filters (wavelength range 400-14,000 nm), custom thin-film coatings including anti-reflection, beamsplitters, mirrors, neutral density filters, and wafer-level packaging/optics coatings (400-20,000 nm), and holographic diffraction gratings (200-2,000 nm) covering plane, laser tuning, pulse compression, and concave Rowland-type configurations. Value-added services include precision dicing (down to 1.0x1.0 mm), filter-wheel assembly, and WLP/WLO coating on wafers up to 200 mm in cleanroom environments.

The business model is direct B2B with wholly-owned regional sales subsidiaries: Spectrogon UK Ltd. (Glenrothes, Scotland) covering Great Britain, Ireland, France, Netherlands, and Belgium, and Spectrogon US Inc. (Mountain Lakes, New Jersey) covering the Americas, while the Swedish HQ covers Europe, Asia, Australia, Africa, and the Middle East. More than 80% of invoiced sales go to OEM customers in specialized electro-optics markets: medical diagnostics, industrial process control, robotics, environmental measurements, optical communications, and analytical instrumentation. Pricing is unit-based with publicly disclosed price lists for dicing services, thin-film services, and uncoated windows, and minimal intermediation. Named customers and program references include ESA (Rosetta, Proba-V), NASA/ESA/CSA (JWST MIRI), EUMETSAT (MetOp-SG A1 IASI-NG), OIP Sensor Systems, and Nobel-Prize-attributed research at Lund University. The company holds ISO 9001:2015 and ISO 14001:2015 certifications and complies with RoHS, REACH SVHC, and WEEE directives.

Broad incumbents

• Edmund Optics: Large global optics distributor and manufacturer offering standard and custom optical filters, coatings, and components. Broader portfolio than Spectrogon (lenses, cameras, full optical assemblies) but overlaps in optical filters and BBAR windows.
• Thorlabs: Large vertically integrated photonics equipment and components vendor including optical filters, gratings, and thin-film coated optics. Competes with Spectrogon for OEM filter and grating supply, but operates a much broader catalog.
• Newport (MKS Instruments): Subsidiary of MKS Instruments supplying photonics components and subsystems including optical filters and laser optics. Larger, broad-line incumbent that overlaps with Spectrogon's laser-tuning and pulse-compression grating customer base.
• Horiba Scientific / Jobin Yvon: Global analytical/scientific instrumentation company that also manufactures diffraction gratings (ruled and holographic) for spectroscopy. A broad incumbent in the same grating category Spectrogon serves, with much larger scale and a wider product portfolio.

Emerging players
