Product Description Optical Glass Plate Bk7 and Fused silica Optical Windows for Protection Optical Instruments Product Description Optical Windows are flat, optically transparent plates that are typically designed to maximize transmission in a specified wavelength range, while minimizing reflection and absorption. They are often used to protect optical systems and electronic sensors from an outside environment. Because windows introduce no optical power into a system, windows should be selected based on the material transmission properties, optical surface specifications, and the mechanical properties that match your application. Material PropertiesMaterial properties including the transmission, refractive index, and hardness of the window substrate can be critical for deciding which window is the best choice for your application. The figure below highlights the transmission regions of the different materials Oplens? offers as windows.Product parametersMaterialBK7 and Fused silica typically, Visible optical glass,Infrared optical glass, Colored glass.TolerancesLow precisionStandard precisionHigh precisionGlass Qualitynd±0.001±0.0005±0.0001vd±0.8%±0.3%±0.1%Dimension Tolerance(mm)±0.20±0.100.01/-0.01Thickness Tolerance(mm)±0.20±0.1±0.005Scratch-DigV(80-50)IV(60-40)II(20-10)Wave front Distortion 632.8nmλ per 25mmλ /4per 25mmλ /20 per 25mmClear Aperture80%90%100%Parallelism (arc min)3-5 minutes1 minutes<1 secondBevel0.3±0.20mm×45° or upon requirementCoatingCoating may be available by custom orderCompany Profile Oplens has been committed to providing customers with high-precision optical system solutions over 16 years, covering the complete manufacturing process from the design, processing and assembly of various optical components and mechanics.
