Solar Filter 70mm Black Polymer

Eclipse Shades® Solar Filter – Our Black Polymer Solar Filters are a low cost alternative to our aluminum cell and glass filters. They have been designed with quality and cost in mind. They can be used on telescopes, binoculars, cameras and finder scopes. This is the same high quality material you have come to know in our Eclipse Shades® Safe Solar Eclipse Glasses. Unlike other solar filters, our black polymer solar film will provide a more pleasing and natural Yellow-Orange image of the sun. This color also offers more contrast and clarity than other solar films. The advantages of this material is that it is stronger and more durable than other thin film solar filters. The actual filtering properties are protected within the substrate. Patent Pending How to size a Filter to fit your Telescope or Binoculars: Your solar filter cell fits over the outside of the telescope or lens holder. This is the same when covering a pair of binoculars or a finder scope. Measure the outside diameter (O.D) of the device and choose the filter size with the inside dimension (I.D.) of the cell larger than the lens holder. Do not choose a filter the same size as your O.D. This will be too tight and not allow room for the felt lining which you will use to tightly fit the filter to your device. Felt tape is included for custom fitting with each filter. Warranty: The safety of this product is guaranteed by ensuring the coating has a transmission of 0.001% or less. The R-G solar film, 2+ Solar Glass Filter and Black Polymer is tested before shipment. If the film or filter has arrived damaged it will be replaced free of charge. Do not use any film that shows any form of defect. Please contact us for further return instructions. All solar filters are covered by a limited liability warranty from defects in material and workmanship. Watch: How to Fit A Solar Filter
