We select optical material which has high refractive index, this may reduce the thickness of the lens, at the same time simultaneously the radius increases, thus obtains the larger field of view.
Doublet objective is composed with the convex and negative lens, the convex one’s material is LAK11 and K9, the concave one’s material is ZF1.
