The SuperK FIANIUM OCT series share the same robust platform as our standard SuperK FIANIUM systems and runs 24/7. They are broadband, low-noise sources designed for optical coherence tomography. Paired with a broadband spectrometer, these sources give the same performance as Ti:Sapphire-based OCT systems at much lower cost, smaller footprint, great mobility, and robustness.

The SuperK FIANIUM OCT supercontinuum laser series has the lowest noise on the market. Optimized for low-noise performance, it gives high-contrast low-noise images in OCT systems. Its performance matches that of costly and bulky Ti:Sapphire lasers.

Below are shown two OCT images of a human eye. The image on the right is recorded using a SuperK FIANIUM 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.




The SuperK FIANIUM series is perfect for applications in need of high-performance beam output. Diffraction limited output from a proprietary collimator design ensures a superb single-mode, broadband collimation at high power.

Filtering and beam steering operations are made precisely due to the high pointing accuracy and broadband beam collimation. Finally, the excellent single-mode Gaussian beam quality ensures the coupling of light back into the single-mode fiber at efficiencies up to 70%.


Built on the world’s best-selling supercontinuum laser, the SuperK FIANIUM has upgraded electronics and new fiber technology giving you the best performance and reliability on the market. And it is even easier to use – no laser expertise needed.

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.

The SuperK FIANIUM is a cost-effective and user-friendly alternative to Ti:Sapphire solutions.


Operating the SuperK FIANIUM OCT is easy and intuitive for all users, no laser expertise is needed. Get supercontinuum light at a press of a button!

The emission button lets you switch the light on and off without the need to reduce the optical power or wait for the system to warm up or cool down. In standby mode, the laser remembers the latest power or current setting and returns to the same level when the emission is re-activated.

You can get access to all laser functions from the SuperK CONTROL graphical user interface on a PC.


The robust system is fully modular, allowing easy operation and service where accessory modules can be added without configuration – all plug & play. 

Functions can be changed on-the-fly without powering down the system.

All NKT Photonics products are produced under our quality management system certified in accordance with the ISO 9001:2015 standard. Force_ISO_logo Laser_warning_class_4
