Silicone Lens
Monocrystalline silicon is an infrared optical material with excellent comprehensive cost performance. Optical grade Czochralski silicon (OCZ-Si) as a transmission grade material is widely used in the mid-infrared (3-5um) band, and the infrared transmittance exceeds 50%. Zone-melted monocrystalline silicon can be used in a wider band (1-14um), and high-purity zone-melted monocrystalline silicon (HPFZ-Si) can even be used in the far-infrared band (greater than 30um).

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
