Nikon Widefield Achromat Brightfield Condenser Lens, 0.85 N.A. (numerical aperture) with iris diaphragm for Nikon product line 3132 Scientific CF Optics. For objective magnifications 4X to 100X without adjustment. It is on a dovetail slider for precise interchangeability.

If you have never used one of these condensers for low power, you are in for a treat! The field is filled with even light and the image contrast and color saturation are superb!

The condenser is absolutely new having only been unwrapped to photograph. Recent list price was $495.00. The diaphragm is in smooth operating condition and all glass is free from dust, scratches, fungus and element separation.
