SuperKSELECT

Multi-channel tunable AOTF filter

Acousto-optical tunable filters
give wide spectral coverage

SuperKSELECT

Tunes over one octave of optical frequency

Applications

The SuperK SELECT is a tunable wavelength filter based on
Acousto-Optic Tunable Filters (AOTF).

Spectroscopy
Single-line laser replacement
Fluorescence-Lifetime

AOTFs tune over one octave of optical frequency and the SuperK
SELECT can integrate two AOTF crystals to provide wide spectral
coverage, thereby giving easy-to-use and flexible access any

BENEFITS

2SuperKSELECT

Ease of use
Built-in intelligence and RF switch
When the SuperK SELECT is connected to the SuperK FIANIUM,
the CONTROL software automatically recognizes and initializes
the SELECT.
SuperK SELECT also features a built-in RF switch for toggling between the two AOTFs without physical cable connection changes

Options
Fiber delivery via SuperK CONNECT
The SuperK SELECT can be combined with our high-performanceSuperK CONNECT fiber delivery system.
It comes complete with broadband fibers and a range of termination options such as FC/PC connectors or high-quality collimators.
Interfacing is handled by the CONNECT fiber coupling block
which ensures easy and stable single-mode coupling that can be
disconnected and reconnected without alignment.
Power Lock - External power stabilization
The Power Lock option enables you to lock the power output of
the SuperK SELECT via a built-in photodetector. Simply connect
the detector to the External Feedback BNC connector of theSuperK.

Features400-2000 nm tuning range
Up to 16 simultaneous, freely
tunable channels
Dual VIS/nIR, VIS/IR, nIR/IR port
accessEasy connection to SuperKFIANIUM
Robust and compact industrial
designMaintenance-free 24/7 operation
Simple and intuitive user interface, NKT Photonics CONTROL, viaSuperK FIANIUM

Activate locking from the control panel to make the SuperK lockthe power output of the SELECT. Power Lock monitors areavailable for both output ports.
The long-term stability of a locked output will typically be better
than +/- 0.5 % (over many hours), depending on the wavelength.
