Spectral variants and power levels
SuperK EXTREME is the industry’s most efficient supercontinuum lasers with the highest visible to total power ratio. High efficiency means better reliability and less unwanted residual pump power at the output.
The SuperK EXTREME comes in five standard models.
|FIU-15||1500 mW||5.5 W|
|EXR-20||2000 mW||6.0 W|
|EXR-9 OCT||900 mW||6.5 W|
|EXW-4 OCT||400 mW||6.5 W|
|EXU-6 OCT||600 mW||6.5 W|
Should you require more power, our SuperK lasers can easily be upgraded to a higher power level.

SuperK EXTREME OCT
With a wavelength range from 400-2400 nm, the SuperK OCT lasers are broadband low-noise sources designed for optical coherence tomography. Use them for optical coherence tomography in the visible wavelength range as well as in the 1300 nm region. The ultra-broad output and low noise make SuperK supercontinuum lasers the ideal OCT source when micron-resolution is needed or when you need a special wavelength range.
Paired with a broadband spectrometer, these sources give the same performance as Ti:Sapphire-based OCT systems at much low cost, lower foot-print, and with great mobility and robustness.
Low noise ensures high-contrast images
The SuperK EXTREME 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 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.
Power Lock (external power locking)
The Power Lock option enables you to lock the power at any place in a setup.
Simply place a photodetector at the desired location and connect the detector to the External Feedback BNC connector of the SuperK laser.
Activate locking from the control panel and the system will now lock the power level at the position of the photodetector—automatically compensating for any drift or variation in external components up to 100 Hz.

Ready-to-use with fail-safe operation
The SuperK EXTREMEseries is easy to use and provides supercontinuum light at a press of a button! The emission button also lets you switch the light on and off immediately, 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.
The jog wheel system makes it easy to operate the laser. Functions such as constant power/current mode, repetition rate control, and laser status can be chosen effortlessly. The Constant Power Mode function allows linear variation – from 0-100% – of the VIS output power.
Modular architecture for flexibility and easy upgrading
The SuperK EXTREME series has a truly modular design, allowing easy on-site support or upgrades.
Due to the unique modularity, upgrading a SuperK laser has never been easier. Unsure of how much power you need? Not a problem. Start with a low-power model and upgrade with high-power modules when you need them. Easy and cost-effective.
The on-board electronics record all operational aspects of each module, enabling you to download a full operational history for monitoring or servicing requirements.
Reliability and long lifetime
The core of the SuperK EXTREME series is based on the world-renowned Crystal Fibre Photonic (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 EXTREME series has ensured the longest continuous running lifetime in the market.
The SuperK EXTREME series is a real alternative to traditional laser sources in OEM or industrial applications, where reliability and cost of ownership are key factors when choosing the most appropriate light source technology.
High beam quality
The SuperK EXTREME series provides the perfect solution 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.
The deployment of the SuperK EXTREME series in Leica’s SP8 X confocal microscope lets its users perform high-resolution diffraction-limited microscopy due to the superior beam quality.
High pointing-accuracy and broadband beam collimation ensure filtering and beam steering operations are made precisely. Finally, the excellent single-mode Gaussian beam quality ensures the coupling of light back into the single-mode fiber at efficiencies of over 70%.
Connectivity and plug & play accessories
The SuperK EXTREME series has a range of functions allowing the user to monitor and expand the functions of the source. Standard output triggering and synchronization functions, such as NIM, are provided for downstream control of the equipment.
Pulse timing signals are available for monitoring the status of the SuperK EXTREME series under a variable repetition rate. More importantly, the series is equipped with a digital communication bus interface for intelligent communication with the SuperK accessory suite.
No need for complicated driver downloads, just plug in the accessory and let the SuperK EXTREME do the rest!
