Product Name: Custom IR Optical Si /Silicon Single Crystal Windows with Ar Coating Model NO.: Silicon windows Coating: Silicon Windows Customized: Customized Certification: RoHS, ISO9001, CE Lenses Color: Black Material: Silicon Shape: Flat Transmittance: >95% Type: Optical Windows Usage: Lighting, Medical, Optical, Photography Trademark: YBT Transport Package: Inner Packing----Special Protective Packing for Op Specification: customized Origin: Shen Yang Product Description Product DescriptionOptical windows are falt, plane parallel plates which are often used as protective barriers for electronic sensors or detectors from outside environments. When selecting windows, please consider materials, transmission, scattering, parallelism and resisitance to certain environment or mechanical properties of the substrate.Silicon (Si) WindowsSilicon (Si) Windows manufactured from optical grade silicon are popular for the 1.2 - 7μm spectral region due to their low cost and low density. Due to its low density (half that of germanium or zinc selenide), silicon is ideal for weight sensitive applications, especially those in the 3 - 5μm region. Density is 2.329 g/cm3 and Knoop Hardness is 1150, making it harder and less brittle than germanium.Diameter0.2-300mmThickness0.1-100mmDimension tolerance+/-0.1mm or +/-0.02mmSurface quality (scratch & dig)60/40, 40/20 or betterClear aperture>85%, >90%Surface accuracyL/10 L/2 LParallelism+/-3' ,+/-30''Bevel0.1~0.3mm x 45 degreeCoatingAR, BBAR or CustomShenyang Ebetter Optics Co., Ltd. offers standard and high precision optical windows in round,square, wedge shapes. We also support custom made optical windows in a variety of substrates, such as UV Fused silica, N-BK7, Germanium(Ge), Silicon(Si),Zinc Selenide(ZnSe). The high precision parallelism of 10 arc seconds, surface quality of 10/5 and flatness of λ/20.Single layer or multi-layer anti-reflection coatings are available.
