optical germanium lens - An Overview
Blog Article
Plano-convex Ge lenses are flat on a person aspect and convex on one other. These lenses Have a very optimistic focal duration, and are sometimes used for gentle collimation.
For an entire breakdown of how you can go through all the big optical window options Test our optical window manual.
It has special Houses of transmission and Index of Refraction in the infrared spectrum which satisfies it for infrared optics. Though our eyes are unable to see through Germanium, infrared radiation (Specially 8-fourteen um) is extremely transmissive via it.
Ahead your materials requirements and We are going to react with a estimate. For any other inquiries or thoughts remember to Get in touch with our educated gross sales personnel.
Germanium retains the significant floor With regards to transmission selection getting that extra protection from seven-16µm, which silicon lacks. On top of this, germanium has better electrical conductivity rendering it a far more suitable candidate being an optical part in laser systems.
Wafers : as a semi conductor material, like Silicon, it truly is greatly employed as a thin substrate for Digital part.
Each monocrystalline and polycrystalline Ge may be utilized for manufacturing of optical parts. We produce Germanium lenses and windows for infrared thermal imaging programs and pyrometry (see our webpage Germanium windows and lenses for thermography).

Infrared Filters, Windows and canopy Glass for Hermetic check here Solder Sealing We acquire and manufacture a variety of optical filters. They may be accustomed to Enhance the efficiency of radiation detectors and influence the signal-to-sounds ratio or reaction sensitivity on the detector. The coatings are well suited for workpieces produced from this sort of elements as germanium, silicon and sapphire.
Germanium can be a large index materials that is certainly utilized to manufacture Attenuated Complete Reflection (ATR) prisms for spectroscopy. Its refractive index is such that Germanium would make a successful natural 50% beamsplitter with no need to have for coatings.
Coatings from Jenoptik assist you to manual beams within a specific method. They filter certain wavelengths, mirror optics or redirect them and decrease reflection if expected. We provide the subsequent:
Alternatively, You can utilize liquid CO2 from the specialized nozzle for cleansing while this needs extra Price tag in terms of apparatus.
Following, the crystal is processed into the desired form utilizing precision reducing, grinding, and machining methods to obtain the precise flatness or curvature required.
