The Best Solar Filters

Whether you’re an astronomy enthusiast, a student, or a professional, studying the sun can be a breathtaking experience you’ll remember for years to come. However, direct solar viewing without proper eye protection can be very harmful to your vision. Any time you want to witness a solar eclipse, or study sunspots on the surface of our closest star, always put safety first.

For guaranteed safe direct solar viewing, pair your favorite telescope, binoculars, camera, or finder scope with one of the best solar filters on the market: the Black Polymer 101mm Solar Filter from Rainbow Symphony.

How Our Solar Filters Stand Apart

Our solar filters are the best on the market because they’re designed with quality and low cost in mind. Made from our exclusive scratch-resistant, grade five optical density Black Polymer, each solar filter is designed to filter out 100% of ultraviolet and infrared light, as well as 99.999% of intense visible light, for guaranteed safe solar viewing.

Unlike other solar films on the market, our filters provide a natural yellow-orange image of the Sun that is both high in contrast and clarity. All of our Black Polymer 101mm Solar Filters are durable, CE Certified, meet the standard for ISO 12312-2:2015, and meet the transmission requirements of scale 12-16 of EN 169/1992.

Find the Right Solar Filter for Your Needs

Our solar filters are designed to fit on the outside of your telescope or binoculars. To find the right solar filter for your needs, measure the outside diameter of your viewing device and choose the filter that has an inside dimension slightly larger than your device’s outside diameter. If our 101mm Solar Filter is not compatible with your device, feel free to browse through our other options. To ensure a snug fit, felt tape is included with each purchase.
