Up for sale is a Olympus NeoS Plan 100X bright dark microscope objective.  This objective has an infinity tube length (TL) and is used on the Olympus BHMJL series of reflected light microscopes.  This is a dry objective with an n.a. of 0.90.  The optics are perfect with all glass surfaces being free from fungus, dust, scratches, chips and element separations.  So common on objectives with small working distances, the front element will be scratched or cracked, NOT THIS ONE, IT IS OPTICALLY PERFECT.  If you are not totally thrilled with this objective, I will gladly refund the purchase price!
