SOUTHAMPTON, England, June 30, 2011 — Ultrafast fiber laser manufacturer Fianium Ltd. has released its SuperChrome filter, a high-power transmission filter accessory for use with its supercontinuum laser sources and fiber delivery systems. The single-channel filter enables the user to select the wavelength and to tune the bandwidth with a switching time of <1 s. It operates over the entire visible spectrum from below 400 to greater than 750 nm, realizing the blue-enhanced region available from the company’s SC400 supercontinuum series. It offers typical transmission of >80%, with maximum performance achieved using filter bandwidths ranging from 8 to more than 50 nm, which is useful for applications such as fluorescence imaging, spectroscopy and superresolution microscopy. When the filter is coupled to the company’s brightest supercontinuum source, the SC450-8-VE, more than 100 mW of power, tunable across the visible range, is available in a 25-nm bandwidth. The unit provides high levels of out-of-band suppression, typically 40 dB, meaning that no additional filters are required for challenging fluorescence lifetime and imaging measurements. The filter enhances the flexibility of the supercontinuum laser output, offering a tunable laser source at any user-defined wavelength. It has no measurable impact on the laser beam quality, with the filtered free-space collimated output having an M2 value of better than 1.2 at all wavelengths. The unit is plug-and-play, requires no user alignment and has an easy-to-use graphical user interface for operation.
