Pair Binocular Solar Filters (45mm filter aperture), Fits tube ODs 51mm to 56mm
NOTE: To ensure proper fit of the solar filter you must measure the outside diameter of the of the binocular barrel (not the lens diameter). To convert inch measurements to metric, multiply your diameter measurement that is in inches by 25.4. This will give you the diameter in millimeters.
Note that any of our filters can be used for binoculars so if the sizes below are not big enough, check the list of our single filters for the proper size and buy two.
