JT Spectra Thermal Lens (Yellow)

JT lenses pass the American ASTM standard and the European CE Standard, but testing doesn't stop there. JT shoots them, stomps them, hits them with 1/4 inch steel balls at 400 fps, runs over them and lets the dog chew them. And that proves one thing - JT lenses meet an even higher standard - the JT Standard. With a fog-resistant coated thermal inner lens that can be cleaned with a JT micro fiber cloth, the standard has been lifted even higher to include pure optical style.
