Pictured is a Nikon Chroma QDOT 655 Fluorescent microscope filter. It is for the Nikon E400/600/800 and TE200/300 inverted microscope. It is new and comes in a plastic container that is not pictured. The Chroma number is 32012. Thanks for looking.

Qdot®conjugates have several special features, including extremely slow color fading, and it is winning acclaim as a new labeling tool for fluorescence observation. Nikon now offers a dedicated Qdot®
detection filter, which maximizes the performance of the fluorescent probe.
The quantum dot conjugate is made from nanometer-scale crystals
of semiconductor material, and the color of light that they emit
differs depending on the particle size. Qdot® conjugates are
nanocrystals for labeling biomolecules such as antibodies and
streptavidin. Unlike conventional organic dyes, Qdot® offers the
following advantages:
(1) Extremely slow color fading and long-term photo stability
(2) Extremely high fluorescence intensity
(3) Extremely sharp detection of wavelength distribution, enabling
the simultaneous detection of different colors without any overlap
(4) Compatible with all manner of optical microscopes, including confocal microscopes.
