What Opto-Line International does
Opto-Line International, Inc. is a privately held, US-based custom precision optical-pattern manufacturer founded in 1967 and headquartered in a 9,800 sq ft facility in Wilmington, Massachusetts. The company combines photolithography (UV/optical lithography) with thin-film coating via high-vacuum evaporation chambers to deposit custom precision patterns on optical substrates at minimum feature sizes of approximately 1μm and edge acuity of ±1μm. Its proprietary low-reflecting black chrome coating (Rave <5%, OD >4.0) and its ability to pattern curved surfaces (concave/convex lenses) are highlighted as distinctive technical capabilities not commonly offered by stock-reticle vendors. Supporting services include blanket and patterned photoresist coatings for semiconductor test wafers up to Ø300mm in a Class 100 clean room, and thin-film deposition of metals, alloys, and dielectrics across substrate sizes from 1mm × 1mm parts to 12.5-inch diagonals.
Opto-Line serves aerospace, military and defense, medical (endoscopy, ophthalmology), metrology, and R&D customers globally. Named reference customers include NASA's Juno mission (sun sensors via Adcole), Applied Materials, Meta, MTPV Power Corporation, Stanford University, and UC San Diego. The company is ITAR-compliant, positioning it as an approved supplier for US defense optics programs. Product lines span apertures, beam splitters, EMI grids, reticles, lens patterning, resolution test targets, and multi-density resolution masks, with each job engineered to customer specification rather than supplied from a stock catalog.
Revenue is generated through a quote-based, project-driven custom-manufacturing model with no public pricing. Go-to-market is direct enterprise field sales led by Paul Sumner (President and CEO), with phone and website quote-request channels and thought-leadership content marketing through the company's blog and social media profiles. The company has 11–50 employees, no disclosed institutional funding, and no parent company, subsidiaries, or acquisitions on record.

Opto-Line International product offering
Product offeringCore offering
Opto-Line International manufactures custom precision optical patterns on customer-supplied or in-house optical substrates using photolithography and thin film coating processes. Core deliverables include custom apertures, reticles, EMI grids, beam splitters, lens patterns (convex/concave), multi-density resolution masks, and resolution test targets, alongside blanket and patterned photoresist coatings for semiconductor wafers processed in a Class 100 cleanroom. The company serves aerospace, defense, medical, metrology, and research customers worldwide with quote-based, project-specific pricing.
Product overview
Opto-Line International is a custom precision optical pattern manufacturer offering a unified portfolio centered on photolithography and thin film coating services. The core offering is Custom Precision Patterns, which encompasses multiple product types including apertures, beam splitters, EMI grids, resolution test targets, reticles, lens patterning, and multi-density resolution masks. Supporting services include Photoresist Coatings (blanket and patterned coatings processed in a dedicated class 100 cleanroom) and Thin Film Coatings (high-vacuum evaporation of metals, alloys, and dielectrics). The company operates as a custom patterning specialist rather than a coating house, combining these capabilities to deliver final precision optics to customer specifications across aerospace, defense, medical, and research markets.
