產品系列說明

  • 具備極高的表面硬度與化學品抵抗力
  • 穿透波長的範圍涵蓋紫外線至中波紅外
  • 較標準玻璃窗口片厚度更薄、強度更大
  • 提供覆蓋 350 - 5000nm 的防反射塗層選項

TECHSPEC®藍寶石窗口片採用單晶體藍寶石製造,由於具備極高的表面硬度、高導熱性、高介電常數以及對常見化學酸與鹼的抵抗力,因此非常適用於需求嚴苛的應用 (例如雷射系統)。藍寶石是硬度位居第二 (僅次於鑽石) 的晶體,由於結構強度很高,因此製造藍寶石窗口片時,厚度可較其他常見電介質窗口片薄得多,而穿透能力更優。從化學角度而言,藍寶石是單晶體氧化鋁 (Al2O3),在穿透0.33 - 5.5μm的光時很有用。透過覆蓋 350 - 5000nm 的塗層選項來提高可見光、近紅外線和紅外光譜的性能。

Optical Windows Review

Optical Windows provide protection between an optical system or sensitive electronics and an outside environment.

I need a window for imaging underwater. The water is filtered and at room temperature with a very small amount of detergent in it. It is flowing at low speed. Will a MgF2 coated window survive this for a few years?
