Additionally, a common concern with IR applications is their tendency to produce a large amount of heat. A material's index gradient and coefficient of thermal expansion (CTE) should be evaluated to ensure the user is met with the desired performance. CTE is the rate at which a material expands or contracts given a change in temperature. For example, germanium has a very high index gradient ...
