![]() OPTICAL WINDOWS Optical Windows are typically flat, plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments. They are as a rule built from two flat, or usually described as plano, polished surfaces that are optically transparent and intended to separate, seal, or else protect other components. With both sided manufacturing process, it yields outstanding parallelism and transmitted wavefront making it idyllic for visible windows in industrial and biomedical applications and military or defense applications. Optical Windows should be carefully chosen based on the material transmission or mechanical properties of the substrate. These Windows do not cause change in the magnification of a system. You can find Optical Windows in a variety of substrates, such as Germanium (Ge), Silicon (Si), N-BK7, UV Fused Silica, Zinc Selenide (ZnSe), or Potassium Bromide (KBr). There are multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR) at Coe Optics. With the so wide spectrum of applications such as in medical, defense, industrial and scientific fields, custom fabrication is required many a times for IR windows , UV, and visible windows in a variety of custom sizes, shapes, and substrates to appropriate the use. So, high precision optical windows with features as given below is customized to specifications that is needed: High-volume capabilities Outstanding parallelism and transmitted wavefront Diameter up to 750mm Thickness up to 100mm Operate in UV, VIS and IR Transmitted Wavefront Error (TWE) better than λ/20 At Coeoptics.com, optical windows are made using strictly controlled fabrication methods, allowing them to function reliably in a range of extreme environments. Customization not only meet the specific needs, but they are created uniquely that requires state-of-the-art fabrication technologies. Optical Windows made from the following optical substrate materials and some additional options might be available with the manufacturer which you can ask for if needed. Crystal Display Glass Fused Quartz Fused Silica IR Materials Low Expansion Optical Glass Types of Optical Windows Ultraviolet Windows Visible Windows Infrared (IR) Windows Besides to flat and wedged optical windows, you can explore additional options that are offered like high vacuum conflats with windows, Brewster windows that eliminate p-polarization reflectance, and UV fused silicon windows designed to be oriented at 45° AOI. OPTICAL LENSES Optical Lenses are created to focus or diverge light. Optical components that make Optical Lenses may consist of a single or a multiple element. And, are used in a wide variety of applications from microscopy to laser processing. There are numerous fields where it is used such as life sciences, imaging, industrial, or defense. When light passes through a lens, it is influenced by the lens’ substrate. A Plano-Convex (PCX) or Double-Convex (DCX) lens causes light to focus to a point, while a Plano-Concave (PCV) or Double-Concave (DCV) lens causes the light traveling through the lens to diverge. When you need color correction Achromatic Lenses are ideal, and for correcting spherical aberration Aspheric Lenses are devised. To transmit the Infrared (IR) spectrum Germanium (Ge), Silicon (Si), or Zinc Selenide (ZnSe) lenses are perfect, while Fused Silica is ideal for the Ultraviolet (UV).
