    Description

    Convex lens in mount for HP / Hewlett Packard / Agilent / Keysight lasers.  This is used in the N1211A laser and is collimator, NOT a beam expander.  It has a single glass positive lens that is used to collimate the ~10 mR divergent beam from the tube into a ~1.5 mm beam.  The position of the lens is adjustable via a threaded mount over a few mm distance (but the seal may need to be freed up with a heat gun to unlock it).
    The focal length is between 6 and 7 inches with a clear aperture of 3/8 inch in the mount, probably larger if the lens is removed.
    The mounting hole patterns for HP 5517/5501B etc. lasers.  The length is just under 1-1/2 inches and the diameter of the flange is 1-5/8 inches.
    To repeat: This is NOT a beam expander, but a single lens collimator.
    But it may be used to convert most HP/Agilent 5517/5501B/5518A/5519A/B lasers to a ~1.5 mm beam for lab applications.  It's just screwdriver work.
    Thanks for looking,
