Half Ball Lens

Half Ball Lens

The hemispheres of the Half-ball lens have uniform light dispersion and are commonly used in LED screens and LED traffic lights, focusing and coupling light. It has many advantages over silicone lens and plastic lens.
Our half-ball lenses are made from BK7, B270, Fused Silica, Sapphire and more. We can also deliver custom Half-Ball lenses and alternative materials in a range of diameters.
