Our germanium lenses have a large refractive index—the very best refractive index amid available IR transmitters. It also reveals minimum chromatic aberration resulting from low dispersion.
Our output workers uses precision CNC curve turbines to create finest-in-course germanium lenses for almost any of one's necessities — from prototype requests via complete production volumes.
Forward your product specifications and We'll answer which has a quote. For any other inquiries or thoughts please contact our proficient profits employees.
You surely don’t would like to breathe in germanium dust so treatment need to be taken even though dealing with these optics. Making use of gloves whenever attainable and washing palms need to be A part of any typical working process.
One cautionary element to note is that your germanium window will never appreciate staying exposed to significant temperatures. Actually, There is certainly an inverse partnership to temperature and transmission In relation to this product. As your temperature goes up, the transmission Qualities will drop precipitously, a property generally known as thermal runaway.
Another similarity is that anti-reflective coatings can be placed on the two visible light-weight digital camera and IR digicam lenses to further improve overall performance by lessening the loss of sunshine and Electrical power that might replicate from the surfaces of your lens if there was no optical coating.
Avantier Inc. is surely an unparalleled chief optical germanium lens in offering imaging units options and optical solutions.
Coatings: Specialized anti-reflective coatings and solutions can even further enhance the general performance of germanium optics by lowering reflection and absorption, strengthening transmission, and rising durability.
Aspherical germanium lenses : intended and useful for Increased optical Attributes and for purposes that need bodyweight conserving. Germanium can be diamond changed into large area excellent aspheres.
Most of the Uncooked material arises from China, Russia and USA staying also critical suppliers, top quality product is offered just about everywhere.
Both germanium and germanium oxide are clear to infrared radiation and so are generally Utilized in the creation of spherical lenses and windows for prime performance infrared spectroscopes and thermal imaging programs.
Manufacturing custom made germanium lenses for top-effectiveness optical apps demands abilities in germanium optics, advanced products for instance CNC curve turbines, and highly managed production processes.
Uncooked germanium have a relatively regular transmission while in the IR (less than fifty%) but Anti-replicate or DLC treatments do boost quite a bit it’s transmittance.
