In 2010, STC was the first to use semiconductor technology to take great optical glass and transform it into something exceptional. Our patented Ultra Layer® coating technology takes high quality optical glass and makes it even better. Multiple coatings make our products hydrophobic, waterproof, smudge proof, and scratch resistant.
Our engineers can block out specific frequencies of light (UV, variable neutral density, IR, and so on) and giving creators more options. Our astrophotography filters are well-known for their light pollution capabilities allowing you to capture the Milky Way from the city!
Our attention detail even includes rimming our filters with carbon to eliminate internal reflection. We spare no expense in grinding our optics to extreme tolerances. And we use CNC technology to create precise parts out of aerospace grade aluminum. We consider ourselves lucky to be able to leverage all the advanced technology in Taiwan that you cannot find elsewhere.
