AMHERST, N.H., Feb. 4, 2013 — Guild Optical Associates has found a way for metallized endoscopic optics to better withstand harsh sterilization techniques. For years, metallized sapphire windows stayed the same while autoclave technology evolved. Now autoclaves and chemical sterilization units are so advanced that they are eating away at the common metallization used to adhere the sapphire windows to their endoscopic housings. The company has delivered a new, more durable metallization. Its new solderable sapphire window can better withstand harsh autoclaves, as well as the new chemical and plasma sanitization systems. The metallized sapphire windows are not limited to the endoscopy industry. The metallization has a higher stress and shock tolerance, making them suitable for all hermetic brazing applications. The new metallic combination is coated on the edges of the sapphire optics and can be used in the same way current optics are soldered or brazed into place.
