Our spherical plano-concave germanium lenses are primarily accustomed to diverge a beam from a collimated light source, or to boost the focal length of the optical program.
It's special Qualities of transmission and Index of Refraction in the infrared spectrum which suits it for infrared optics. Regardless that our eyes can not see by Germanium, infrared radiation (In particular 8-fourteen um) is extremely transmissive by means of it.
Send out us your precise prerequisites, and our technological gross sales representatives will review what is needed to provide All set-to-use factors inside of your guide time.

The two monocrystalline and polycrystalline Ge may very well be employed for producing of optical parts. We create Germanium lenses and Home windows for infrared thermal imaging programs and pyrometry (see our webpage Germanium windows and lenses for thermography).
Click on the various class headings to understand much more. You can also transform a number of your preferences. Note that blocking some sorts of cookies may possibly effect your experience on our Internet websites along with the companies we can give.
Specialised measurement and inspection: Using specialized measurement equipment and inspection machines, we ensure that the surface roughness, curvature, along with other essential parameters meet up with strict tolerances and high quality expectations.
There are plenty of technical troubles in producing germanium factors for infrared optical methods, like preserving large optical good quality in excess of a wide array of temperatures, minimizing unwelcome radial resistivity gradients, and lowering the absorption of infrared radiation.
It's got excellent transmission in the 8 to fourteen µm selection masking the thermal Infrared mild, hence it truly is a material of choice for thermal and night time vision. It also exhibits a substantial refractive index which enable large open up aperture angle optical ingredient’s design and style.
Equally germanium and germanium oxide are transparent to infrared radiation and so are commonly Employed in the creation of spherical lenses and windows for top performance infrared spectroscopes and thermal imaging units.
Knowing the difference between different lens kinds can help pick which a person to use when in an effort to get most troubleshooting data.
Uncooked germanium have a relatively regular transmission inside the IR (a lot less than fifty%) but Anti-replicate or DLC therapies do improve a great deal it’s get more info transmittance.
