EO Edmund's Zinc Selenide Infrared Aspheric Lenses offer a diffraction limited focusing performance. They are recommended for focusing the output of a CO2 laser. The lenses are provided uncoated or they are incorporated along with a broadbancd anti-reflection coating offering a high transmission from 7.5 - 13.5μm.
The Zinc Selenide is a toxic material that is why it should handled with double care. The operator must wear gloves which are made up of plastic or gloves to prevent contamination.
