Paper Abstract

The optical properties of glasses are traditionally characterized out to 1 micron in most catalogs, yet, the useful spectral range can extend out to as far as 4 microns. For this reason, the temperature and frequency dependent infrared properties of the Schott glasses Suprasil 300, Ultran 20, SK4, SF6, F2, BK7, UBK7 and KzFSN4 have been measured. This is accomplished by broadband transmittance and reflectance measurements as a function of temperature from room temperature up to 600 degree(s)C. The infrared absorption edge of these glasses is analyzed and modeled with a theoretical multiphoton model and oscillator model. The refractive index of these glasses in the infrared region is estimated from the measurements and a Sellmeier model extending into the infrared is now obtained.
