Silicon is brittle and easily cracks even under a small load. The difficulty in shaping silicon has prevented breakthroughs in the mass production of silicon lenses for terahertz and infrared technology. We developed a novel method of deforming bulk single-crystal silicon into the required shape by one-shot pressing and realized the near-net shaping of silicon into a plano-convex shape with the curvature radius R = 7:5 mm. The crystallographic quality of the obtained lens was improved by primary recrystallization. By packaging it into a practical sensor module, the suitability of the lens for practical application was demonstrated.
