Our spherical plano-concave germanium lenses are primarily used to diverge a beam from the collimated light-weight resource, or to improve the focal size of an optical process.
5µm. This leaves germanium as the ideal and only option for brutally tricky IR applications. This is typically why you will see germanium windows and lenses serving in locations as inhospitable as outer House, battlefields and in the course of significant-powered CO2 laser units. Additional on this later on.
Ahead your materials requirements and We are going to answer having a estimate. For another inquiries or questions make sure you contact our knowledgeable product sales team.
Germanium holds the substantial floor With regards to transmission selection having that extra coverage from 7-16µm, which silicon lacks. On top of this, germanium has larger electrical conductivity rendering it a far more appropriate applicant as an optical ingredient in laser systems.
Be sure to bear in mind that this could intensely lessen the performance and look of our website. Variations will just take effect when you finally reload the webpage.
Shanghai Optics manufactures quality germanium lenses in a range of popular measurements, from 5m m to 350 mm in diameter.

Coatings: Specialized anti-reflective coatings and therapies can further more greatly enhance the general performance of germanium optics by reducing reflection and absorption, increasing transmission, and escalating longevity.
Curiously, on account of its identical crystal structure to Diamond is usually coated having a DLC layer (Diamond Like Carbon) which along with reducing the reflection on it’s surface area, provides a diamond powerful protective layer. Eventually Germanium just isn't transparent within the visible which can be valuable to concentrate on IR mild.
Germanium winds up in some attention-grabbing areas including defense aircraft navigation, reconnaissance and surveillance devices soaring inside the stratosphere on an plane or at the same time as Portion of a satellite.
