Intrinsic Silicon

Intrinsic silicon crystal is a pure and crystalline silicon crystal formed by purifying silicon materials. The characteristics of intrinsic silicon include high purity, low defect density, and excellent optical transmittance, which make intrinsic silicon have broad application prospects in optical component manufacturing. It can process shapes such as circular, rectangular, perforated, crescent, wedge-shaped, flat convex, flat concave, double convex, double concave, open ball, and prismatic. UM OPTICS has complete optical crystal production equipment and experience, and can provide high-quality intrinsic silicon crystals.
