NONI offers custom chalcogenide lens for infrared optics application. Chalcogenide glass is a type of glass that contains one or more chalcogen elements such as sulfur, selenium, or tellurium. It has been shown to display various advantageous properties for use as a lens material, both when used alone or in combination with other materials. These glasses transmit primarily in the midwave-infrared (MWIR) and LWIR wavebands, making them suitable for thermal imaging applications.
