Filters and Accessories for SuperK Supercontinuum Lasers

The SuperK Supercontinuum Accessory range has been designed to further increase the flexibility of the SuperK supercontinuum light sources. The accessories allow access to either particular spectral ranges or specific wavelengths within the ultra broad SuperK spectrum. All accesories are “plug and play” with any SuperK supercontinuum laser, which then controls and powers the accessory.

Tunable filter models

Bandwidth Wavelength range Variable bandwidth Fast wavelength switching Fiber delivery Suppression No of channels
LLTF 2.5 / 5.0 nm 400-1000 nm / 1000-2300 nm 60 dB 1
SuperK VARIA 10-100 nm 400-840 nm 50 dB 1
SuperK SELECT 0.5-20nm 400-2000 35 dB 1-16
LLTF tunable high contrast single line filter

The LLTF Contrast is a continuously tunable high-resolution bandpass filter that effectively converts a NKT Photonics’s supercontinuum source into a widely tunable picosecond laser. The filter transmits, with high efficiency, a single laser line while blocking unwanted lines with excellent out-of-band suppression. Read more »

SuperK VARIA tunable single line filter

The SuperK VARIA is a cost effective and flexible alternative to a monochromator, effectively turning the SuperK supercontinuum laser into a powerful single-line laser with a 440 nm tuning range and variable bandwidth. The center wavelength of the pass band can be tuned anywhere between 400 and 840 nm and the bandwidth is variable between 10 and 100 nm, making the SuperK VARIA the most flexible filter solution on the market.

SuperK SELECT multi-line tunable filter

The SuperK SELECT is a tunable multi-wavelength filter based on Acousto-optic Tunable Filter technology (AOTF). AOTFs tune over one octave of optical frequency and the SuperK SELECT allows the integration of two AOTF crystals to provide wide spectral coverage. The SuperK SELECT provides an easy to use, flexible and accurate tuning accessory to access any wavelength in the SuperK spectrum. Read more »

SuperK SPLIT spectral supercontinuum splitter

The SuperK SPLIT is a passive filter which allows the SuperK spectrum to be divided into two spectral outputs. This is important in applications where light from one sub-area of the spectrum is desired and light outside this spectrum is parasitic. Read more »

SuperK CONNECT broadband fiber delivery

SuperK CONNECT is a unique high performance fiber delivery system complete with broadband fibers and a range of termination options such as FC/PC connectors or collimators. Interfacing is handled by the CONNECT precision fiber coupling unit that ensure easy and stable single-mode coupling that can be disconnected and reconnected without alignment. Read more »
