Our germanium lenses Have got a substantial refractive index—the highest refractive index among the readily available IR transmitters. It also displays nominal chromatic aberration as a result of reduced dispersion.
It's also well worth noting that germanium is relatively much more brittle that silicon and for that reason need to be cope with with treatment in the course of machining.
If significant transmission is the only real thing to consider, you’d be finest served to double coat your windows with BBAR above particular wavelength ranges and you may see transmissions the many way up to 99%. Now we’re chatting!

They can even be Utilized in focusing apps, and also have widespread use in many fields, from science to marketplace to defense. We endorse these lenses be oriented so the flat facet faces the desired focal airplane.
Each monocrystalline and polycrystalline Ge might be used for producing of optical factors. We develop Germanium lenses and windows for infrared thermal imaging programs and pyrometry (see our webpage Germanium windows and lenses for thermography).
The amount of holes current could be lessened by increasing the amount of electrons with the addition of team V atoms (donors) to your Ge. This lowers resistivity. Extreme addition of donors results in abnormal electron concentration and elevated absorption.
We build and manufacture optical components in the very best high quality you could use in a number of fields of application, from laser substance processing to biotechnology, healthcare technological know-how, defense and stability as well as the semiconductor sector.
By developing only one crystal, we create parts which has a consistent crystal construction and significant purity.
These high-excellent cylinder optics are ideal for use in laser scanning, laser projection, beam homogenization and PCB fabrication. They are also a great Remedy in fault analysis.
Both of those germanium and germanium oxide are transparent to infrared radiation and so are generally Utilized in the manufacture of spherical lenses and Home windows for top performance infrared spectroscopes and thermal imaging techniques.
Being aware of the distinction between different lens sorts may also help determine which 1 to employ when website so as to get most troubleshooting details.
Raw germanium have a relatively typical transmission while in the IR (fewer than fifty%) but Anti-mirror or DLC remedies do strengthen a great deal it’s transmittance.
