A Simple Key For optical germanium lens Unveiled

It also reveals small chromatic aberration resulting from low dispersion.
5µm. This leaves germanium as the most effective and only choice for brutally hard IR programs. This is typically why you will note germanium Home windows and lenses serving in areas as inhospitable as outer Room, battlefields and in the middle of high-run CO2 laser techniques. Additional on this later on.
Germanium has outstanding thermal stability. It might endure higher running temperatures without having degrading optical functionality.

Avantier Inc. is definitely an unparalleled chief in giving imaging devices alternatives and optical methods.
It's the Distinctive hardness of germanium that provides it its distinctive ruggedness; Ge features a Knoop hardness of 780. It is a superior density substance, at 5.33 g/cm3, and allowances has to be manufactured for this fat For anyone who is creating a excess weight delicate process.

We provide precision cylinder lenses in round, rectangular or quadratic designs to meet your specifications. The optical factors are available with higher-reflection or antireflection coatings for the DUV, UV, VIS and IR spectral ranges. The Exclusive coating improves the cylinder lenses and would make them a lot more resistant. Details Sheet
Accomplishing a typical inspection of electrical gear round the manufacturing unit; whenever you’re taking images and looking at gear near you and nearer to eye-degree can make use of the standard lens.
It's great get more info transmission from the 8 to fourteen µm variety masking the thermal Infrared light, thus it's a cloth of choice for thermal and night time vision. What's more, it shows a substantial refractive index which enable large open up aperture angle optical component’s design and style.
The sharp transmission Lower-off just before 2µm also permits germanium to be used as a long move filter, only transmitting wavelengths in extra of 2µm and absolutely blocking everything in advance of it.
UQG Optics most effective-sellers like Germanium Home windows are available coated and uncoated in a variety of diameters and thicknesses.
Optical windows : most important utilization of germanium with Great transmission inside the IR and no transmission during the noticeable. Normally, germanium windows are strengthened with DLC coating on just one encounter.
