Silicon Lenses used for imaging at 3-5μm region

Silicon Lenses

Czochralski (Cz) Silicon is commonly used as a substrate material for infrared reflectors and Lenses in the 1.5 μ m-8 μ m region. It is frequently used for laser mirrors because of its high thermal conductivity and low density. Silicon is also a useful transmitter in 20 μ m range.
Silicon lenses are popular for many applications in the IR System. They are typically used for imaging applications in the 3-5 μ m region of the spectrum, making them excellent for security and military applications. They can also be used to collimate infrared lasers. These lenses are coated with a BBAR coating that provides 98% transmission in the 3-5 μ m spectral range.
CRYSMIT manufactures silicon lenses with diameters ranging from 3 mm to 200 mm. We offer options for AR coating or DLC coating to enhance their performance and durability.
