Supply kinds of Plano convex Si-lens, Bi-convex Si-lens, Plano
concave Si-lens, Bi-concave
Si-lens (Infrared Silicon Lenses).
Silicon (Si) is grown by Czochralski (CZ) pulling techniques. CZ
Silicon is commonly used as substrate material for infrared
reflectors and windows in the 1.5 - 8 micron region. The strong
absorption band at 9 microns makes it unsuitable for CO2 laser
transmission applications, but it is frequently used for laser
mirrors because of its high thermal conductivity and low density.
Applications: window, lens in the
1.5 - 8 m region and mirrors for CO2 laser and spectrometer
applications
