What Janos Technology does

Janos Technology, LLC is a U.S. precision optics manufacturer founded in 1970 and headquartered in Keene, New Hampshire, specializing in advanced infrared (IR) optical components. Its product portfolio spans MWIR and LWIR lens assemblies, diamond-machined refractive and reflective lens elements, off-axis parabolic and other metal mirrors, and custom thin film coatings (AR, HCAR, BBAR, DLC, high-reflectance metallic) deposited on substrates such as Germanium, Silicon, ZnSe, ZnS, AMTIR, and GaAs. Core manufacturing capability is built around seven CNC two-axis single point diamond turning machines capable of parts up to 430mm in diameter, supported by CNC generating and centering equipment and extensive metrology, with demonstrated figure accuracy to 1/10 λ per inch and surface roughness as low as ≤5 Å RMS.

The company operates as a B2B build-to-print manufacturer serving defense, commercial, and security end markets. It sells primarily through direct enterprise engagement via phone and email, with custom engineering collaboration on specifications rather than off-the-shelf catalog distribution. Revenue is generated through one-time product sales of custom IR components and professional build-to-print design and prototyping services, with quote-based pricing (no public price list), a $250 minimum order threshold, and net-30 U.S. dollar payment terms. The company is ITAR registered, ISO 9001:2015 certified, MIL-STD qualified, and DFARS/NIST 800-171 compliant, enabling participation in U.S. defense supply chains.

Janos became a Fluke company in 2008; Fluke is itself a wholly owned subsidiary of Fortive Corporation (NYSE: FTV), a diversified industrial conglomerate. Janos has no publicly disclosed funding rounds, no named end-customer logos, and operates from a single manufacturing site, serving as a specialized niche supplier of high-precision infrared optics within the broader Fortive portfolio.
