Silicon is the principal component of most semiconductor devices, most importantly integrated circuits or microchips. Silicon is widely used in semiconductors because it remains a semiconductor at higher temperatures than the semiconductor germanium.
Yutai Optics standard silicon windows feature a clear aperture of at least 90 percent of the central dimension. They have a surface quality of 20-10 scratch dig; which means there are no digs (pits) with a diameter of more than 0.1mm, and no scratches longer or deeper than that designated by 20 in MIL-PRF-13830B. The lower a scratch dig number; the better the quality of an optic; industry standard is generally 80-50, with 20-10, like ours, being high precision quality.
