Blue-Violet Excitation: BV-2A (Longpass Emission)

The Nikon BV-2A fluorescence filter combination includes a medium-width bandpass excitation filter (400-440 nanometers) coupled with a longpass barrier filter (470-nanometer cut-on wavelength) to enable signal collection from a wide range of fluorescent probes. The BV-2A filter set utilizes a dichromatic mirror with the same 455-nanometer cut-on wavelength specification as the BV-1A block, providing a 15-nanometer separation from the barrier filter cut-on.

Blue-Violet Excitation Filter Block BV-2A Specifications

Excitation Filter Wavelengths: 400-440 nanometers (bandpass, 420 CWL)
Dichromatic Mirror Cut-on Wavelength: 455 nanometers (longpass, LP)
Barrier Filter Wavelengths: 470 nanometer cut-on (longpass, LP)

The BV-2A fluorescence filter set is designed to perform with a wide range of fluorochromes excited by blue-violet wavelengths, and is the standard Nikon blue-violet filter block. By employing a medium-width excitation passband in conjunction with a longpass barrier filter, this filter set (along with the BV-2B set) produces the brightest images of the blue-violet group. The BV-2A filter combination is recommended when studying the following fluorophores: aminochloromethoxyacridine (ACMA), acridine homodimer, acriflavin, aminopyrene trisulfate (APTS), Alexa Fluor 430, Astrazon Yellow, atabrine, berberine sulfate, beta-lactamase (non-ratiometric), catecholamine, cyan fluorescent protein (CFP), Calcofluor White, Chromomycin A, chlorotetracycline (CTC), Lucifer Yellow, mithramycin, quinacrine mustard, Sevron Yellow, and thioflavine S.
