产品特点
The Double Convex Lenses are made from Fused Silica material, which are manufactured with an identical convex surface on both sides of the lens. The Double Convex lenses have positive focal lengths and form both real and virtual images. We also provide precision grade Double Convex lenses with tighter manufacturing tolerances.
