    Germanium Optics

    Germanium (Ge) Optical Components are used in many Infrared (IR) applications or systems, including thermal imaging, spectroscopy, or with monochromatic light sources such as quantum cascade lasers. German (Ge) Optical Components are Optical Components designed for high performance in the Infrared (IR) spectrum without the use of Infrared (IR) anti-reflection coatings. Germanium (Ge) Optical Components can range from Optical Lenses to Prisms or Optical Filters.

    Edmund Optics’ offers the world’s largest inventory of off-the-shelf Optical Components, including a wide variety of Germanium Optics. Edmund Optics’ Germanium Optics include Optical Lenses, Optical Windows, Optical Filters, or Prisms. Edmund Optics’ Germanium (Ge) Optical Lenses include Aspheric Lenses, Hybrid Aspheric Lenses, Achromatic Lenses, Plano-Convex (PCX) Lenses, or Meniscus Lenses. Germanium (Ge) Prisms include equilateral or right angle. Edmund Optics offers Germanium (Ge) Longpass Filters for isolating broad regions of the Infrared (IR) spectrum, in addition to Neutral Density (ND) filters for even attenuation of Infrared (IR) light.
