    Description

    The 71-6204 4 inch Magnet Back Mirror is used to check the perpendicularity of any flat surface to the line of sight by means of auto-collimation or auto-reflection. This is the big brother of the 71-6202, made by both K&E and Cubic Precision. The mirror is flat to 1/4 wave, and the three magnetic feet on the back are then precision ground to be parallel to the mirror face within 3 seconds of arc. NSN 6650-00-219-3379
    The device is in very good cosmetic condition. Comes with original box and focus sheets.
