Introduction A composite is a complex solid material, made by combining two or more dissimilar materials in such a way that the resulting material is endowed with some superior and improved properties [1].
Composite materials are light weight, high strength to weight ratio and good stiffness property.

Because there are a limited number of lens materials that are used in MWIR spectral bands, in order to balance chromatic aberration, the silicon material was adopted as positive focal lens because it has high index and low dispersion.
We can derive the equivalent Abbe’s number and relative partial dispersion of BOE by the following formulas, Aspheric surfaces and diffractive surface were set up on germanium material to ensure they were easy to process Coefficient of rotationally symmetric BOE is shown as Tab.2
