Check the listing for details. Olympus Microscope Quintuple Nosepiece & Objectives BH Series. Condition: Used. Listed at 175.00 USD. Olympus BH microscope quintuple objective nosepiece with 4X, 10X, 20X, 40X and 100X oil immersion objectives. To my knowledge this objective turret dovetail will only fit the Olympus BH series of the 1970's, however the objectives will work on other Olympus microscopes of the era and also the Nikon Lk and Sk series of the same vintage. All of the optics are in excellent condition without dust, fungus, scratches or element separations. The objective turret moves freely and the stops are positive and firm, cosmetically, this lot is in nice condition. (Location A-3)
