The Definitive Guide to optical germanium lenses

We offer you an index of saved cookies on the computer in our area to help you Look at what we stored. Resulting from protection factors we are unable to clearly show or modify cookies from other domains. You'll be able to Check out these in your browser safety configurations.

Based on the software, we implement hugely sturdy and productive antireflection coatings towards the factors. This can make them resistant and enhances transmission. We also examination them in accordance with DIN ISO or MIL specifications.

Something more than one hundredºC is not proposed. By the point it reaches two hundredºC it is almost opaque whatsoever wavelengths. If you need a significant temperature window, you’re improved suited to stay with a fabric like MgF2, YAG or our old Buddy sapphire.

Fabrication: Our specifically produced managing and machining approaches enable to get rid of sub-surface area damage and chipping. We retain a number of top rated-high-quality multi-axis CNC vertical mills dedicated to machining sophisticated lenses in either output or prototype quantities.

Wafers : as being a semi conductor product, like Silicon, it is widely used as a skinny substrate for Digital component.

Equally monocrystalline and polycrystalline Ge could be useful for manufacturing of optical elements. We create Germanium lenses and windows for infrared thermal imaging applications and pyrometry (see our webpage Germanium windows and lenses for thermography).

It can be Lower, polished and shaped into lenses and windows Utilized in infrared detector equipment and also infrared spectroscopes.

Germanium ends up in a few fascinating areas which include protection aircraft navigation, reconnaissance and surveillance methods soaring inside the stratosphere on an plane or even as Component of a satellite.

The sharp transmission cut-off in advance of twoµm also enables germanium to be used as a protracted pass filter, only transmitting wavelengths in extra of 2µm and absolutely blocking anything prior to it.

Material Variety: Significant-quality germanium substrate is vital for manufacturing superior-overall performance lenses, as any defects or impurities while in the germanium crystals could impression the optical Attributes of your concluded lens. Rely upon Lattice to deliver superior-quality tailor made-developed germanium to guarantee significant-excellent lenses.

Uncooked germanium material is rather tough but can however effectively be machined and polished into optical components:
