How to Repair Steiner Binoculars

Steiner Binoculars makes optics for bird and wildlife viewing and field use. Highly calibrated optic lenses bring far-off views in close for observation. Inert gases fill the binocular's chambers to keep them fog-free. Many models use adjustable chambers and focus dials. Steiner requests that all binoculars with lens issues be sent back to the company where professional technicians recalibrate or grind the glass. Small repairs are acceptable to do at home.

      Check all screws on the optics. Many Steiner models have a dial screw between the two optic barrels. If loose, the barrels flop and don't hold when adjusted. Remove the screw and remove any grease or accumulated grime from the screw. Place the screw back on and tighten it using a flathead screwdriver.

      Check all the Steiner eyepieces or rubber end caps for cracks. Dry rot causes cracks along rubber. If dry rot is present, use some clear glue to seal the cracks on the dry rot. Take care to not get glue on the lenses.

      Check the diopter-setting ring along the eyepiece on the optics. This ring turns to bring the two barrels' views into stereo (aligned vision). Check that it rests flush with the base of the optic barrel. If it doesn't, push it down to the barrel chamber.

      Pour lens cleaner on a chamois cloth and wipe off each lens of the Steiners. Use a dry spot on the cloth to dry the lenses after cleaning. After cleaning the lenses, blow away any dust with compressed air (the cans sold at computer stores to clean keyboards work beautifully).
