Nikon UV-2A Fluorescent Microscope Filter Cube for Eclipse E400/600/800, TE200/300

Product Description

Nikon UV-2A Fluorescent Filter Cube for the Nikon Eclipse series of microscopes including the E400/600/800, and TE200/300 Inverted. The Nikon product number is 96100. The filter is new, having come from a former Nikon microscope dealer's inventory. Thank you for looking!

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. 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

The UV-2A fluorescence filter combination is designed to provide all-purpose imaging of fluorescent specimens with ultraviolet excitation, and is considered the standard set for this spectral region. The 50-nanometer bandpass excitation filter covers the longer ultraviolet wavelengths and is capable of exciting many of the fluorophores that have marginal absorption in this region. The longpass emission (barrier) filter employed in the UV-2Acombination is designed to collect signals at wavelengths exceeding 420 nanometers, enabling visualization of red, green, and blue emission from fluorophores excited in the ultraviolet. The UV-2A filter combination is recommended when studying the following fluorophores: Alexa Fluor 350, 7-amino-4-methylcoumarin (AMC), and its acetic acid derivatives (AMCA-S and AMCA), anthroyl stearate, bisaminophenyloxadiazole (BAO 9), bisbenzamide, Calcein Blue, Cascade Blue, dansyl derivatives, 4'-6-diamidino-2-phenylindole (DAPI), dopamine, Fast Blue, FluoroGold, Hoechst 33258/33342, noradrenaline, Nuclear Yellow, pyrene, tetracycline, and True Blue.
