    Description

    University Optics Or 40mm 1.25mm orthoscopic eyepiece
    This is an extremely rare eyepiece. I have personally only encountered this one specimen. I do not know its age or the exact history behind it, but it might be a prototype or a limited production eyepiece.
    The apparent field of view is not specified, but I would estimate it to be between
    40° and 45°
    . The eye lens is recessed about 20mm from the rim of the eyecup.
    Optical performance is
    excellent
    .
