Infrared Transmitting Glass Ceramics A Review

Some examples of infrared transmitting glasses.

Infrared transmitting glass ceramics a review.

Depending on the wavelengths being used a number of glass materials can be considered. The key factor for controlling the glass to crystal transformation in an infrared transmitting glass ceramic is in the selection of a suitable glass composition which must have the two following specificities. A review mccloy john s. Qiao amy 2013 06 04 00 00 00 a large body of literature was reviewed with the aim of identifying binary and ternary systems for producing long wave infrared transmitting glass ceramics for window applications.

Applications for infrared ir transmitting glass ceramics have included far infrared fibers 21 scintillators 22 24 nonlinear optical devices 25 26 and bulk optics. Known optical and physical property data was summarized for many ternary sulfides as well as their constituent binary sulfides. Cs based crystals have been generated inside the glass matrix and the crystal size is controlled to be less than 100 nm in order to keep the transparency of the composite materials. A large body of literature was reviewed with the aim of identifying binary and ternary systems for producing long wave infrared transmitting glass ceramics for window applications.

Glasses as well as glass based ceramics offer the advantage of unique rheological properties. We have studied the mechanical properties of a new family of infrared transmitting glass ceramics based on the ges 2 sb 2 s 3 cscl system. The demand for infrared materials which exhibit higher performance is still growing. A large body of literature was reviewed with the aim of identifying binary and ternary systems for producing long wave infrared transmitting glass ceramics for window applications.

First when heated above t g this glass has to precipitate nanosize particles and avoids a fast growth of each individual nano crystal. Both on the thermal and mechanical side as well as on the width of the optical window with an extension of the transparency towards the long wavelength region to satisfy the requirements of space applications.
