Product description

Silicon (Si) is grown by Czochralski pulling techniques (CZ) and contains some oxygen that causes an absorption 

band at 9 microns. To avoid this, material can be prepared by a Float-Zone (FZ) process. Optical silicon is generally 

lightly doped (5 to 40 ohm cm) for best transmission above 10 microns, and doping is usually boron (P-type) and 

phosphorus (N-type). After doping silicon has a further pass band: 30 to 100 microns which is effective only in very 

high resistivity uncompensated material.

CZ Silicon is commonly used as substrate material for infrared reflectors and windows in the 1.5-8 micron region. 

Note for Silicon Window:

(1). Custom-made Silicon windows at any size are available.

Besides round, shape of quadrate, triangular, or other polygonal are available.

(2). Thickness from 1.0mm to 80.0 mm is available upon request.

(3). Better bevel is available upon request.

(4). Si Windows with Anti-Reflective(AR), High-Reflective(HR), Partial-Reflective(PR) coating are available.
