Deposition Sciences Inc. is offering a low-pressure chemical vapor deposition process that applies durable coatings to irregularly shaped objects and that is designed for almost all types of optical glass, including ball lenses, crystalline materials, ceramics and metals. The high-temperature process (~500 °C) uniformly coats the interior and exterior surfaces of an object. The deposition method is thermally driven to deposit multiple layers of silicon dioxide, tantalum oxide and titanium dioxide, as needed. The layers are resistant to thermal shock and can be deposited on optics as small as 0.3 mm.
