Tunable wavelength filter with variable bandwidth

The unique SuperK VARIA is a cost effective and flexible alternative to a monochromator, effectively turning the SuperK supercontinuum white light source into a powerful single-line laser with a 420 nm tuning range and variable bandwidth. The center wavelength of the pass band can be tuned anywhere between 400 and 820 nm and the bandwidth is variable between 10 and 100 nm, making the SuperK VARIA the most flexible filter solution on the market. 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.
