SuperK COMPACT – cost-effective supercontinuum white light lasers

The SuperK COMPACT is a cost-effective supercontinuum white light source that gives you diffraction-limited light in the
450-2400 nm range. It is over 100 times brighter than incandescent lamps and has greater bandwidth than ASE sources or SLEDs.

Use it for component characterization, test & measurement, spectroscopy, or as a general-purpose laboratory white light source. Its monolithic fiber architecture gives you a stable, reliable, and maintenance-free laser.

A versatile light source

The SuperK COMPACT can be found in laboratories around the world where it is the daily driver for many users within applications like component characterization, test & measurement, spectroscopy, and OCT or simply as a general-purpose laboratory white light source.

The SuperK COMPACT can be triggered externally and synced up to 20 kHz. The trigger signal can be provided to a standard coax input or to the industrial trigger input that is galvanically isolated.

High reliability and a 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.
