Germanium windows and lenses for IR infrared thermography – sales@dmphotonics.com Germanium windows and lenses Germanium lenses (Ge lenses) is commonly used in IR imaging systems typically operating in the 2 µm to 16 µm spectral range, covers the LWIR (8-12μm) and MWIR (3-5μm) thermal imaging applications. Gerrmanium has the highest refractive index of commonly available IR-transmitters and has low optical dispersion. This makes it desirable in aspects of lens design where its refractive index allows otherwise impossible specifications to be built. Germanium can be AR coated with Diamond producing an extremely tough front optic, and it is often used as the front optics in lens group. Germanium is more rugged than other IR materials, but caution should be taken for high temperature applications where the material will become opaque in the IR realm as the temperature rises. Beside the general spherical surface lenses, we also provide the aspherical surface lenses made by SPDT (Single Point Diamond Turning) technique. Diameter range: ~ 300mm Long wavelength range from 2 to 16 micro Fit for both MWIR (3-5 micro) and LWIR (8-12 micro) thermal imaging applications All types of lenses: plano-convex, plano-concave, double convex, double concave and meniscus With spherical and aspherical lens surface Various types of coating available: AR/AR@7-14um DLC (diamond or hard carbon coating)/AR@7-14um BBAR/BBAR@3-12um Customized coating Specifications Materials – Optical grade germanium single crystals Diameter range ~300mm Diameter Tolerance -0.01/-0.03mm Thickness Tolerance +/-0.03mm Surface Quality 60/40 S/D Fringes (N) – 3 Irregularity (delta N) -1 Centration – 3′ Chamfer – 0.1-0.3mmx45 degree Coatings AR/AR@7-14micro DLC/AR@7-14micro BBAR/BBAR@3-12 micro For coating curves – email to sales@dmphotonics.com Germanium (Ge) is a relatively hard, high-density, IR transmitting material that blocks UV and VIS wavelengths but allows IR from 2µm. Germanium has the highest refractive index of commonly available IR-transmitters and has low optical dispersion. This makes it desirable in aspects of lens design where its refractive index allows otherwise impossible specifications to be built. AR coating is recommended. Typical applications for Germanium include thermal imaging where the material can be used as a front optic while its index of refraction makes Germanium useful for wide-angle lenses and microscopes. Additionally, Germanium components can be used for FLIR (Forward Looking Infrared) and FTIR (Fourier Transformed Infrared) spectroscopy systems, alongside other analytical instruments. In order to lower the cost and improve the imaging quality of les assemblies used in thermal imaging cameras, the aspherical surfaces is used in the design of lens group. We provide the spherical surface lenses made by SPDT (Single Point Diamond Turning) technique. =================================
