Blanks

MATERIAL - Si (Silicon)


Crystaltechno LTD makes optical blanks from different types of optical crystals and glasses.

Optical standard Si (Silicon) blanks can be further polished to usual windows, lenses and prisms or shaped to some special customers' design. Crystaltechno Ltd. manufactures optics from following Silicon Si material.
Silicon is grown by Czochralski pulling techniques (CZ) and contains some oxygen which causes an absorption band at 5.8, 9.1 and 19.4 microns. To avoid this, Si monocrystalline material can be prepared by a Float-Zone (FZ) process.

Crystaltechno Ltd. manufactures Si blanks: maximum diameter of Si-Cz blanks - up to 300 mm, maximum diameter of Si-Fz blanks - up to 100 mm.
