Silicon(Si) Plano-convex Lens
Silicon has high thermal conductivity and low density. Silicon is a widely used NIR material for applications in the 1.2 to 7 μm region due to its low cost and low density. Silicon is well suited for weight-sensitive applications, especially those in the 3 -5 μm range.
Our company offer silicon plano-convex lenses in various sizes and focal lengths.
