Infrared Silicon PrismsSilicon (Si) is one of the hardest minerals and optical materials available for use in the NIR (1µm) to about 6µm. Optical quality Silicon is usually doped (5 to 40 ohm cm) to prevent absorption bands within the transmission waveband. Silicon has a lower refractive index than germanium and has a lower density that makes for less weighty optical designs. Wuhan Especial Optic has been engaged in high precision IR prisms for over 10 years. We can custom Germanium prism, Silicon prism, ZnSe prism, CaF2 Prism as per your drawing or detailed specs. State of the art testing devices are the key gor our quality assurances.
