What Phasics does
Phasics SA is a Saint-Aubin, France-based photonics company that designs and manufactures high-resolution wavefront sensors, quantitative phase imaging (QPI) cameras, and integrated optical metrology test stations based on its patented Quadriwave Lateral Shearing Interferometry (QWLSI) technology. Founded in 2003 with QWLSI introduced commercially in 2004, the company's SID4 sensor family covers an industry-leading spectral range from 190 nm deep UV to 14 µm long-wave infrared, including specialized variants for vacuum environments (SID4 HR V), dual-band MWIR/LWIR (SID4 DWIR), and life-science imaging (SID4 sC8, SID4 Bio). The company extends its hardware into application-level systems through the Kaleo MTF, Kaleo MultiWAVE, Kaleo IR, and Kaleo Kit test stations, plus PhaseStudio measurement software and OASys adaptive optics control software compatible with deformable mirrors from multiple third-party vendors.
Phasics serves enterprise customers across eight primary verticals: semiconductor lithography, automotive ADAS and LiDAR, life sciences and medical research, defense and surveillance, laser and optics manufacturing, astronomy and space, AR/VR consumer electronics, and emerging quantum computing applications. Its technology is validated by 24+ peer-reviewed scientific publications and partnerships with French research institutions including Institut Fresnel, Ecole Polytechnique (LULI), Onera, and Institut d'Optique.
The company operates a hybrid go-to-market combining direct technical sales with an authorized distributor network (PHASICS CORPORATION in Boulder, Colorado; Opto Science in Japan; Onset Electro-Optics in Taiwan; and direct China presence). Revenue is generated primarily through hardware sales of wavefront sensors and integrated test stations, supplemented by custom OEM integration projects and professional services, with quote-based pricing on multi-year contracts. Phasics was acquired by French electro-optical group Exosens in 2025 and now operates as a wholly-owned subsidiary, with product content transitioning to the Exosens platform.
