Intrinsic silicon currently has three grades and is widely praised by customers.
SI-MIRROR grade: single crystal, mainly used in the galvanometer mirrors of various high and low power lasers, standard shapes or customized shapes, typical: no transmittance requirements.
SI-OPTICAL grade: single crystal, mainly used for infrared temperature measurement and imaging purposes such as optical lenses, filters, prisms, etc., typically: higher transmittance requirements.
SI-Wafer grade: single crystal, mainly used in semiconductors, IGBT modules, diodes and triodes, typical: resistance control is extremely strict.
