BLACK POLYMER: Exclusive Thousand Oaks Optical formula developed solely for SAFE solar observation. Unlike metallized Mylar (commonly used in food packaging), our Polymer gives a SHARP pleasing orange image versus unnatural pale blue. Mylar also reflects your eyes in the mirror like surface making it difficult to see the sun. And contrary to claims by some manufacturers, two layers does not guarantee no pinholes in the coatings. Simply hold a Mylar viewer at arms length, close to a light bulb, to see this defect. The protective properties of our Black Polymer are throughout the substrate so there is never a concern about safety. Our Black Polymer is also great for making safe & inexpensive filters for cameras, binoculars and custom solar viewers. It's easy to work with and extremely durable. Instructions included.
