Alnair Labs

What Alnair Labs does

Alnair Labs (株式会社アルネア, Alnair Corporation) is a Tokyo-headquartered Japanese photonics company founded in 2001 that designs, manufactures, and sells fiber optic components and measurement instruments. Its product portfolio spans five categories: ultra-narrowband variable optical filters (BVF/CVF series), narrow-linewidth and swept-source tunable lasers, erbium-doped fiber amplifiers including space-grade variants for satellite applications, high-speed electronic instruments (pulse generators, clock generators, bit error rate testers), and optical measurement instruments such as polarization controllers, OTDRs, and the recently launched SensRay distributed strain measurement system. Underlying technologies include proprietary phase-noise-compensated OFDR, FBG-based filtering, and CubeSat-compatible EDFA/EYDFA designs qualified for space environments. The company monetizes through direct hardware sales (catalog units, modules, and OEM configurations) and custom product development services, supported by a wholly-owned manufacturing subsidiary in Malaysia and sales offices in Taiwan, China, and California. Its customer base is concentrated in three verticals: aerospace/satellite communications, optical research institutions and universities, and — most recently — civil infrastructure monitoring, where the SensRay instrument is co-commercialized with Kajima Corporation.
