The category  of yellow fluorescent protein fluorescence filter comprises a single high-performance balanced combination, this effectively extends the fluorescent protein detection capabilities afforded by the three green fluorescent protein (GFP) filter sets to the longer wavelength enhanced yellow chromatic variants of GFP (YFP and EYFP). The YFP HYQ filter combination employs relatively narrow passband excitation and emission (barrier) filters, which are designed to correspond with the specific spectral characteristics of enhanced yellow fluorescent protein, and enable the fluorescence emission from YFP derivatives to be evaluated separately from that of other fluorescent proteins. In the Nikon YFP HYQ block, excitation is limited to a 20-nanometer band of wavelengths in the blue-green spectral region (495 to 510 nanometers), and is coupled to an emission filter transmitting yellowish-green fluorescence in the range of 520 to 550 nanometers. The longpass dichromatic mirror has a cut-on wavelength of 515 nanometers
