Increasing the bandwidth of the filter has the added advantages of higher power throughput and reduced speckle in imaging applications. Moreover, a high out-of-band suppression of up to 50dB makes the SuperK VARIA an ideal tool for FLIM and other applications using high sensitivity detectors.
The SuperK VARIA is designed to be used with the SuperK supercontinuum sources, but can also used with traditional laser systems or broadband light sources. Use the collimated free-space output from the filter directly or combine the VARIA with the SuperK CONNECT broadband fiber delivery system for pristine single-mode fiber delivery over the entire tuning range in one single fiber.
