We are a startup company founded in March 2018. As noticed by the company title made by combining 'philos,' meaning love, and 'phos,' meaning light, we pursue commercialization of various innovative optical technologies. 

Currently, we are working on low-cost and compact optical coherence tomography (OCT) systems. Like Tesla making EVs out of totally new design, we began from development of core  components, such as spectrometer and light source driver, and then, we made a non-medical OCT system, which is mobile and wireless for the first time, to the best of our knowledge. 

Recently, we are aiming at OCT based retina imaging. They are cost-effective and ultra-compact, which will allow more patients ‌to benefit from this technology through point-of-care diagnostics and tele-ophthalmology.


To brighten the future of mankind by innovative optical technologies


To realize our unique and disruptive biomedical imaging devices

To contribute to humanity

‌To challenge global difficult issues
