Fluorescence Microscopy | Ultraviolet Filter Combinations | UV-2A. Fluorescence Filter Combinations Ultraviolet Excitation: UV-2A (Longpass Emission) The Nikon UV-2A ultraviolet fluorescence filter combination includes a medium-width bandpass excitation filter (330-380 nanometers) coupled to a longpass barrier filter (420 nanometer cut-on wavelength) to enable collection of signals from a wide spectrum of fluorescent probes. Ultraviolet and visible transmission spectral profiles for this filter combination are illustrated below in Figure 1. The common dichromatic mirror for the Nikon UV-2 series of filter combinations has a cut-on wavelength of 400 nanometers and reflects greater than 95 percent of the ultraviolet wavelengths between 330 and 390 nanometers. Ultraviolet Excitation Filter Block UV-2A Specifications: Excitation Filter Wavelengths: 330-380 nanometers (bandpass, 355 CWL) Dichromatic Mirror Cut-on Wavelength: 400 nanometers (longpass, LP) Barrier Filter Wavelengths: 420 nanometer cut-on (longpass, LP)
