NKT Photonics has introduced the SuperK Gauss spectral filter for use with SuperK Extreme supercontinuum lasers for white-light interferometry (WLI) and optical coherence tomography (OCT) applications.
SuperK Gauss spectral filter
It converts the laser’ broadband output to a Gaussian output and offers two bands of wide-bandwidth spectral outputs with an adjustable center wavelength for each band. The port control is offered by manual shutters.
The Gauss spectral filter offers ultra-power spectral output between 800 and 1300 nm via single-mode fiber utilizing the SuperK fiber delivery system for OCT applications. The filter comes with same setup for WLI uses and offers modification of the center wavelength of each band above 200 nm. It offers a similar plug-and-play system and can be connected to the SuperK Extreme easily.
The spectral filter’s output power range is between 70 and 700 mW, spectral width range is between 170 and 200 nm, fiber output is angle polished or fiber-coupled and collimated connector, and wavelength split point is 1050 nm. The laser’s broad spectral bandwidth enhances the axial resolution in WLI and OCT applications.
The supercontinuum laser, along with Gauss filter, offers a uniform spectrum and decreases the number of image artifacts, resulting in high-resolution images down to 2 mm with enhanced details.
NKT Photonics informed that with the Gauss filter, the laser’s resolution is equal to Ti:sapphire lasers and higher than superluminescent diodes. The SuperK industrial supercontinuum lasers and auxiliaries are utilized in biomedical instrumentation for analysis and imaging applications. All SuperK lasers are using a monolithic fiber platform and eliminate warm-up time or alignment and have longer operating life.
