Abstract

The SIG (chalcogenide glass) developed by Sunny Infrared Optics is suitable for all kinds of thermal lenses, especially for molding lenses. It has competitive price and several advantages including stable refractive index, low softening temperature, great material uniformity. However, SIG is relatively soft and easy to be scratched. Sunny Infrared Optics has developed HD (high-durable) coating for SIG to protect the lenses from environmental damage. HD coating combines the best attributes of DLC coating(diamond-like carbon) and AR coating(anti- reflection), while minimizing their disadvantages. For one thing, HD coating is harder and more durable than AR coating, for another, the transmittance of HD coating is higher than DLC coating. HD coating on SIG is becoming a more popular solution for security application from fire protection to border defense.
