The SuperK EXTREME OCT series shares the same robust platform as our standard SuperK EXTREME systems and can be run 24/7 if needed.
The sources can be used for optical coherence tomography both in the visible wavelength range as well as in the 1300 nm region.
The ultra-broad output and low noise make SuperK supercontinuum lasers ideal OCT sources when micron resolution is needed or when you need a special wavelength range.
Reliability and long lifetime
The core of the SuperK systems is based on the world-renowned Crystal Fibre Photonic Crystal Fiber (PCF) technology, which has been deployed in commercial and academic markets for over a decade. NKT Photonics is the largest manufacturer of PCF technology and reliability, quality and performance are ensured through DIN ISO 9000 certified processes.
Continuous testing of multiple systems during and after the development phase of the SuperK systems has ensured the longest continuous running lifetime in the market.

Low noise
The SuperK EXTREME OCT series is the supercontinuum laser on the market with the lowest noise. It is optimized for low noise performance to yield high-contrast low-noise images in OCT systems and in the performance matches that of large bulky Ti:Sapphire lasers.
Below are shown two OCT images of a human eye. The image on the right is recorded using a SuperK EXTREME OCT source, while the image on the left is obtained using a Ti:Sapphire laser. Both images are recorded by Angelika Unterhuber from Prof. Dr. Wolfgang Drexlers group at Medical University Vienna.
