NKT Photonics - Model SuperK SELECT -Tunable Multi-channel Filter for Laser

• 400-2000 nm tuning range
• 16 simultaneous, tunable channels
• Dual VIS/nIR, nIR/IR port access
• Robust and maintenance-free
• Easy connection to SuperK lasers
• Simple user interface via CONTROL

Tunable filtering and built-in intelligenceTunable filtering over two octaves

The SuperK SELECT is equipped with one or two Acousto-Optic Tunable Filters (AOTF), powered by an RF driver. 

The AOTFs allow tunable filtering over two octaves in the visible, nIR, or IR spectra. Each octave has its own optical output. Choose from the standard free-space collimated beam or the optional fiber-delivered output.

Up to 8 wavelengths

Up to 8 wavelengths per channel can be continuously tuned simultaneously for each AOTF and the power of each wavelength can be controlled through the CONTROL software as well.

Built-in intelligence lets you plug and play

Intelligent SuperK accessories communicate with the SuperK FIANIUM via the specially designed communication bus. No need for complicated downloads or configurations. Just plug the accessories in and let the SuperK recognize and install them.

Additional accessories? No problem! The external bus can handle the connection of multiple accessories, so you can expand the uses of the SuperK without any fuss.

The CONTROL software gives you access to all information about the status of SuperK SELECT. 

LEDs on the side panel can inform you about shutter position (Emission), Interlock, applied RF signal, and the supply voltage via the external bus. 

The SELECT has a built-in RF switch that lets you switch between the two AOTFs without cable changes.

Power lock, external power stabilization

The Power Lock options enable 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 the SuperK. Activate locking from the control panel and the SuperK will now lock the power output of the SELECT.

Power Lock monitors are available 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.
