  • Ideal for Thermal Imaging Applications
  • Uncoated Transmission from 2 – 16µm
  • Available Uncoated or BBAR Coated for 3 - 12µm

ISP Optics Germanium (Ge) Plano-Convex (PCX) Lenses provide transmission and low absorption through the Long-Wave Infrared (LWIR) spectrum, making them useful for thermal imaging applications. Germanium is chemically inert and insoluble in water with a Knoop Hardness of 780, making it ideal for applications requiring rugged optics. However, Germanium is subject to thermal runaway and should be used at temperatures below 100°C. ISP Optics Germanium (Ge) Plano-Convex (PCX) Lenses are available uncoated with a broad transmission range from 2 – 16µm or with a Broadband Anti-Reflection (BBAR) coating for enhanced transmission in the Mid-Wave Infrared (MWIR) and Long-Wave Infrared (LWIR).
