SuperK EXTEND-UV supercontinuum extension unit

The SuperK EXTEND-UV is a deep-UV supercontinuum spectral extension unit for our SuperK EXTREME and COMPACT supercontinuum lasers. Get tunable UV light from a robust fiber laser source with 270-480 nm range and 2-80 µW output power.

Excite intrinsic fluorescence from e.g. proteins or take advantage of UV excitable probes like Laurdan, DAPI and AMCA.

The collimated output enables tight focusing and the fast pulses, down to 20 ps in length, make it ideal for studying ultrafast photochemical processes.

The EXTEND-UV is robust and alignment free – simply click in the SuperK collimator and turn on the system. The output wavelength is easily controlled from our CONTROL software our through our SDK.

  • Short pulses down to 20 ps
  • 2-12 nm bandwidth
  • Polarized UV and visible output
  • Powered by the SuperK EXTREME or COMPACT
  • VIS and IR broadband output ports

The SuperK EXTEND-UV is available in two different models; DUV and UV. The performance and output characteristics of the system depends on the Supercontinuum source used. We recommend the SuperK EXTREME EXW-12 or the EXR-15/EXR-20 for maximum average power or the SuperK COMPACT for a very cost effective high pulse energy system.
