Exclusive high quality substrates provide superior safety features, sharper solar images, and pleasing orange solar image.
Formula developed solely for SAFE solar observation. Unlike metalised Mylar (commonly used in food packaging), the black polymer gives a SHARP pleasing orange image versus unnatural pale blue. Mylar also reflects back to your eyes in the mirror-like surface making it difficult to see the sun.
Contrary to some claims, two layers used for redundancy does not guarantee that there are no minute 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 using black polymer are throughout the substrate so there is never a concern about safety.
