Spectrum Telescopes Solar Glass Binocular Filter

Yes, these are full-aperture solar glass filters specifically engineered to block harmful solar radiation. They are designed to allow you to view the sun safely through your binoculars, provided they are securely attached.

These filters are compatible with binoculars that have an objective lens diameter between 105mm and 111mm. You should measure the outer diameter of your binocular's objective lens housing carefully before purchasing to ensure a proper fit.
