Chalcogenide glass components are becoming popular in various IR applications due to its excellent wide band transmittance (3-5µm, 8-12µm) with reliable machinability, which perform rather differently from oxides; particularly low band gaps help optical designers to introduce more flexible IR solutions. Hangzhou Shalom EO offers the customized lenses and balls made from chalcogenide glass materials.

Chinese made IRG series Chalcogenide glass are used, 7 types of Chalcogenide glass are available for your design choice: IRG201, IRG202, IRG203, IRG204, IRG205, IRG206 and IRG207, please contact with us (sales@shalomeo.com) to get detailed data for your confirming and design.
