產品系列說明

  • 波長範圍是1.8 - 12μm
  • 具有多種鍍膜選項
  • 提供有鏡框與無鏡框的解決方案

我們的紅外線非球面透鏡非常適用於多種中波與長波紅外應用。The low-cost, molded design offers several key benefits over Germanium substrate aspheres. With a dn/dT and CTE significantly less than that of Germanium, our lenses feature a smaller change in focal length as a function of temperature change. And, with a higher operating temperature than Germanium (which suffers 20 – 30% transmission loss at 100°C), our lenses can be used in applications that were not previously possible with Germanium.

The Mid-Wave and Long-Wave Infrared (IR) Aspheric Lenses are available with a variety of coating options. For custom requirements, including custom coatings, custom designs, or adding diffractive features to the aspheric surface, please contact our Sales Department.
