SuperK COMPACT supercontinuum lasers

The SuperK COMPACT is a cost-effective supercontinuum white light source delivering diffraction-limited light in the entire 450-2400 nm region with a brightness several orders of magnitude larger than that of incandescent lamps and with far greater bandwidth than ASE sources or SLEDs. The light is delivered in a single-mode fiber terminated with either a standard FC/PC connector or our high-quality collimator.

SuperK COMPACT supercontinuum white light laserThe 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 with low jitter 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.

FeaturesPower density versus wavelength

Combine the COMPACT with a computer-controlled filter from our supercontinuum filter range and turn the white light source into an ultra-broadband tunable laser, and control it all through the NKT Photonics CONTROL software.

The SuperK COMPACT can be configured with three types of output termination:Collimator

  • FC/APC
  • Broadband collimator

The collimated version is compatible with our filtering accessories such as the VARIA and SELECT.
