Silicon window
Silicon (Si) Windows have the advantages of wide transmission band (covering 1.2-7um), low cost and low density, which are very suitable for weight-sensitive applications, especially in the 1.65 - 5μm area.
Wloptical offers high precision optical grade Silicon windows with Flatness of Lambda/10 and Surface Quality of 10/5.
Czochralski (Cz) Silicon is commonly used as a substrate material for infrared reflectors and windows in the 1.5μm-8μm region. It is frequently used for laser mirrors because of its high thermal conductivity and low density. Silicon is also a useful transmitter in 20μm range.
Wloptical manufactures silicon windows with diameters ranging from 3mm to 150mm. We offer options for AR coating or DLC coating to enhance their performance and durability.
