Molding IR Lens
Precision molding of lenses using Chalcogenide glass affords considerably less expensive production cost in large quantities compared to SPDT (single point diamond turning) and a definitive and competitive price-performance ratio. Chalcogenide glass has attractive optical properties over broad IR spectrum range and is suitable for molding manufacturing process. Molding of chalcogenide glass infrared optics allows the precision optics manufacturing of finished, aspherical, spherical, and diffractive lens geometries. These can also be used at temperatures above 80 C as there is no thermal darkening unlike other materials like Germanium.
