Plano-convex Ge lenses are flat on 1 aspect and convex on the other. These lenses have a positive focal duration, and are frequently used for light-weight collimation.
Higher than value are generic requirements for fabrication, unique greater price may very well be readily available and need to be reviewed circumstance by circumstance.
It has exclusive Qualities of transmission and Index of Refraction in the infrared spectrum which suits it for infrared optics. Despite the fact that our eyes can't see as a result of Germanium, infrared radiation (especially eight-fourteen um) is very transmissive by means of it.
Germanium has quite a few positive aspects, making it a suitable product for fabricating spherical lenses and aspheric lenses for many apps in aerospace, defense, and infrared optics.
This enables ideal IR transmission vital to evening vision/thermal imaging. As these Home windows can have excellent sensitivity at long variety, This allows warfighters to retain prolonged stand-off distances rising basic safety and mission-effectiveness. Germanium is usually a literal existence-saver.
Welcome to UQG Optics! It appears like that you are traveling to from the US. Pick out your favored forex down below to view suitable pricing. Speak to us for additional aid or to discuss particular specifications.
Both of those monocrystalline and polycrystalline Ge could be utilized for production of optical elements. We make Germanium lenses and Home windows for infrared thermal imaging apps and pyrometry (see our webpage Germanium Home windows and lenses for thermography).

We provide precision cylinder lenses in spherical, rectangular or quadratic styles to fulfill your needs. The optical parts can be obtained with large-reflection or antireflection coatings to the DUV, UV, VIS and IR spectral ranges. The Particular coating improves the cylinder lenses and would make them much more resistant. Knowledge Sheet
Infrared Filters, Windows and Cover Glass for Hermetic Solder Sealing We develop and manufacture numerous optical filters. They may be utilized to Enhance the efficiency of radiation detectors and influence the sign-to-sound ratio or response sensitivity of the detector. The coatings are suitable for workpieces made from such products as germanium, silicon click here and sapphire.
It's excellent transmission while in the 8 to fourteen µm array covering the thermal Infrared light, hence it can be a material of option for thermal and night eyesight. Furthermore, it exhibits a higher refractive index which help large open up aperture angle optical element’s style.
Jenoptik´s OrthoLine optical alignment cubes are designed mostly for processes that have to have precision datum registration - which includes programs from the life and well being sciences, metrology and defense.
Substance Choice: Superior-good quality germanium substrate is essential for developing large-performance lenses, as any defects or impurities within the germanium crystals could impression the optical Qualities with the concluded lens. Depend on Lattice to offer superior-grade custom made-developed germanium to make sure substantial-quality lenses.
Raw germanium product is quite tricky but can even now efficiently be machined and polished into optical components:
