    Looking for Peak/Micromega Model 1 Manual

    Does anyone have a digitized copy of the Micromega/Peak Model 1 grain focuser? If you could email me it, I'd be very grateful!

    Thanks!

    If you mean the operating instructions, there are no pictures so the entire instructions may be digitized in ascii...

    MICROMEGA CRITICAL ENLARGING FOCUSER
    Catalog Number 468-006

    OPERATING INSTRUCTIONS

    The unusual configuration of the
    focuser, the pivoted eyepiece and the
    length of the mirror (86mm) make the
    Micromega accurate and effective even
    when used off center of the projected
    image. While conventional grain focus-
    ers must be used directly under the lens,
    the Micromega can examine and focus
    any part of the image area up to 30
    degrees from the optical axis of the
    enlarger lens, an exclusive feature. The
    white cavity with center hole is designed
    to permit the user to place a coin on the spot
    of the easel on which he wants to focus
    and then position the Micromega
    precisely by placing it over the coin.

    When positioned on-easel, with a nega-
    tive in place and the enlarger on, the
    Micromega reflects the projected image
    to the eyepiece where it is magnified 10X.
    The rectangular reticle at the focal point
    delineates the "target area" and the en-
    larger is focused until the grain structure
    of the negative is sharp.

    FOCUSING

    Set up the enlarger for printing; size and
    compose the print; throw the enlarger
    into approximate focus, and with the
    mirror cover open, place the Micromega
    on the easel. For highest accuracy, keep
    a scrap of enlarging paper under the
    Micromega to position the base of the
    instrument at the exact paper plane.

    Since the Micromega need not be used
    directly under the enlarging lens, it can
    be positioned to focus the most import-
    ant part of the projected negative.

    Look through the eyepiece and swing it
    on the pivot until the full field can be
    seen brightly. Finally focus the enlarger
    until the granular structure of the
    negative appearing within the double
    framed rectangle is sharp. Remove the
    Micromega and print.

    CARE OF THE MICROMEGA

    Treat the Micromega like the fine instru-
    ment it is. Don't knock it about and don't
    touch the mirror with anything but a fine
    camel hair brush or compressed air.
    Keep the cover down when not using the
    focuser. Clean the eyepiece lenses with
    lens tissue or compressed air if needed.

    SPECIFICATIONS
    Focal Length...25mm
    Lens Construction...3 elements, 2 groups
    Lens Coating...mgf2--all surfaces
    Magnifications...10x
    Viewing Angle from Optical Axis...
    30-degrees via pivoting eyepiece

    Before Using:
    The Micromega is provided
    with a built-in blue filter that can be swung
    into the light path at the top of the eyepiece. It
    is used for black and white enlarging only to
    improve contrast and optimize focusing
    accuracy.

    The first time the Micromega is used, the eye-
    piece must be adjusted to the vision of the
    individual user. With the mirror cover open, in
    normal light or under the enlarger, rotate the
    knurled eyepiece until the double framed
    reticle is sharp. Although this need only be
    done once, check this setting each time you
    use the focuser as a matter of good operating
    procedure.
