Earlier mentioned value are generic technical specs for fabrication, distinct much better price could possibly be obtainable and should be reviewed situation by scenario.
fiveµm. This leaves germanium as the most beneficial and only option for brutally tricky IR applications. This is typically why you will see germanium Home windows and lenses serving in sites as inhospitable as outer space, battlefields and in the course of high-run CO2 laser units. Extra on this later on.
Fabrication: Our specially produced managing and machining strategies assistance to eliminate sub-area injury and chipping. We retain numerous leading-high-quality multi-axis CNC vertical mills devoted to machining intricate lenses in either production or prototype quantities.

Even so, this is where they begin diverging. Silicon is far lighter having a density of two.33g/cm3, which makes it perfect for excess weight-delicate programs and below half the density of germanium. Additionally, it is much more thermally resistant than germanium and by using a Knoop Hardness of 1150 Additionally it is more durable and less brittle. Silicon also expenditures considerably less rendering it a greater prospect in various programs.
Aspherical germanium lenses : developed and utilized for enhanced optical Qualities and for apps that will need body weight saving. Germanium is often diamond became higher area good quality aspheres.
Germanium is actually a significant index product that's used to manufacture Attenuated Whole Reflection (ATR) prisms for spectroscopy. Its refractive index is these kinds of that Germanium will make an effective all-natural 50% beamsplitter with no have to have for coatings.
Creating a solitary crystal of germanium could be the place to begin for production significant-top quality factors. The crystal composition and defect density can substantially influence its optical and electrical Homes.
UQG Optics ideal-sellers for instance Germanium Windows can be obtained coated and uncoated in many different diameters and thicknesses.
Raw germanium product is rather really hard but can nonetheless proficiently be machined and polished into optical check here components:
