Supercontinuum Filters and Accessories

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 accessories are “plug and play” with any SuperK supercontinuum laser, which then controls and powers the accessory.

LLTF Tunable High Contrast Filter

LLTF Contrast

The LLTF Contrast is a continuously tunable high-resolution bandpass filter that effectively converts an NKT Photonics’ 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.

SuperK SELECT

SuperK SELECT

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.

SuperK VARIA

SuperK VARIA

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.

SuperK SPLIT

SuperK SPLIT

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.
