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.

Covers the spectrum from visible to infrared

The LLTF Contrast is a non-dispersive filter maintaining the intrinsic single-mode beam quality of the supercontinuum laser enabling a wide range of applications. With two wavelength tuning options, Visible and NIR, the full spectrum of the supercontinuum can be covered.

Adapts directly to the output collimator

The LLTF Contrast is compatible with all NKT Photonics Supercontinuum lasers and is fully plug-and-play – adapting directly to the supercontinuum output collimator.

The output of the LLTF Contrast is compatible with SuperK CONNECT and SuperK Fiber deliveries (we recommend FD7 for VIS and FD8 for SWIR).

User-friendly interface

The LLTF can be operated through a user-friendly PHySpec software or a direct interface through the free software development kit
