Our germanium lenses Have a very substantial refractive index—the best refractive index among the available IR transmitters. In addition it exhibits minimal chromatic aberration due to small dispersion.
It's also value noting that germanium is fairly additional brittle that silicon and for that reason need to be tackle with treatment all through machining.
Fabrication: Our specially made handling and machining techniques assistance to eradicate sub-surface area harm and chipping. We maintain many best-high-quality multi-axis CNC vertical mills devoted to machining elaborate lenses in either output or prototype quantities.
To see more about Germanium Windows from UQG Optics, or any of our optical windows connect with us on 01223 420329 or e mail our profits crew at [email protected]
Avantier Inc. can be an unparalleled leader in offering imaging devices options and optical remedies.
It’s also a sensible choice for those who’re scanning overhead vents or duct perform, superior-electrical power transmission towers which have been a distance away. The telephoto lens lets you do the job safely from the ground.
The quantity of holes existing can be diminished by expanding the amount of electrons because of the addition of team V atoms (donors) into the Ge. This lowers resistivity. Too much addition of donors causes abnormal electron focus and greater absorption.
We offer precision cylinder lenses in round, rectangular or quadratic styles to fulfill your specifications. The optical parts can be obtained with superior-reflection or antireflection coatings with the DUV, UV, VIS and here IR spectral ranges. The Unique coating enhances the cylinder lenses and can make them extra resistant. Data Sheet
A wide-angle lens expands your thermal digicam lens’ discipline of see. In order to see much more of what’s bordering an asset, or are Doing work in a tight Place, They may be mission significant to have the shot.
Ge lenses can transmit infrared wavelengths devoid of major decline, allowing for for distinct and precise imaging.
Usual resistance for EMI-grade germanium is close to 4 Ohm per cm but this depends on the necessary volume of spurious signal suppression. A germanium window designed to those specs can efficiently small out any errant signals and preserve the IR procedure working very well.
Now for many enjoyable things. We hear from a good amount of our consumers wherever their germanium Home windows are viewing motion. Here are a few highlights:
These are rookie numbers and in the majority of apps we’ll have to have to boost our window signals through numerous coatings. Even though This can be a downside for optical Home windows this house comes in useful for novel lens types and ATR optics the place refraction is sought after.
