Fluorescent labeling in the far-red region of the light spectrum is expanding, as long wavelength dyes can now virtually eliminate sample auto-fluorescence. The new filter sets also provide the wide spectral separation essential for multi-labeling experiments. To aid researchers with these developments, Glen Spectra has expanded its range of filter sets for fluorescence microscopy. Sets are available for the far-red region of the spectrum and cover the most popular excitation wavelength sources, including Ar-Kr, He-Ne and Red Diode Lasers. The XF138-2 ALPHA Vivid set combines an ALPHA shortpass excitation filter, with a 690nm ALPHA longpass filter. It is ideally suited to the use of Ar-Kr mixed gas, He-Ne, and Red Diode laser lines and maximises emission throughput. The XF140-2 ALPHA Vivid set has a wide bandpass excitation filter and is suited to the broader band Mercurcy Hg arc excitation energy.
