TECHSPEC®矽石平凸 (PCX) 透鏡具備精密拋光面，因此特別適用於包括近紅外線 (NIR) 成像及紅外線光譜在內的多種紅外應用。這些透鏡提供從f/1到f/10的多種焦距，無鍍膜或具備廣波段抗反射鍍膜。若有客製紅外線鍍膜需求，請聯絡我們的銷售部門.
Silicon is popular in the 1.2 - 7μm spectral region because of its low cost and low density as compared to other infrared materials. Silicon features a density of 2.329 g/cm3 and index of refraction of 3.422. With a density of less than half that of Germanium or Zinc Selenide, Silicon is ideally suited to weight sensitive applications, especially those in the 3 - 5μm region. Silicon reacts with halogens and dilute alkalis, but is inert to most acids. Silicon’s Knoop Hardness is 1150, making it harder and less brittle than Germanium.
Plano-Convex (PCX) lenses feature a positive focal length and have one flat and one convex surface. They should be oriented with the plano (flat) surface towards the desired focal plane. They are ideal for collimation and focusing applications utilizing monochromatic illumination.
