Our germanium lenses have a higher refractive index—the highest refractive index amongst readily available IR transmitters. In addition, it displays minimal chromatic aberration due to lower dispersion.
This Web site is using a stability services to guard itself from online attacks. The action you simply executed brought on the safety Alternative. There are numerous actions which could cause this block including submitting a particular phrase or phrase, a SQL command or malformed details.
Send out us your distinct requirements, and our complex profits representatives will examine what is necessary to deliver Completely ready-to-use parts within your guide time.
You surely don’t would like to breathe in germanium dust so care has to be taken although handling these optics. Using gloves Anytime doable and washing fingers should be Section of any regular running procedure.
You could electronic mail the internet site operator to allow them to know you were blocked. You should include Everything you were accomplishing when this site came up as well as Cloudflare Ray ID observed at the bottom of the webpage.
We’ve already explored why you'd probably pick germanium in excess of sapphire but why would you pick germanium more than silicon or vice versa?
The end intention is to supply germanium optics that fulfill or exceed the demanding needs of assorted applications, from infrared thermal imaging and sensing to spectroscopy and laser programs.
When this product is guarded by a thoroughly engineered anti-reflective coating, it gets an incredibly efficient materials to transmit Electricity to some thermal camera detector and create large-good quality thermal visuals. The coating is additionally intended with ruggedness in your mind which enhances scratch resistance.
Apparently, because of its comparable crystal composition to Diamond can be coated with a DLC layer (Diamond Like Carbon) which in addition to cutting down the reflection on it’s floor, provides a diamond powerful protective layer. Last but not least Germanium will not be clear during the seen which can be valuable to center on IR light-weight.
Germanium can be a significant index substance that may be utilized to manufacture Attenuated Overall Reflection (ATR) prisms for spectroscopy. Its refractive index is these types of that Germanium will make an effective natural fifty% beamsplitter with no want for coatings.

An uncoated germanium window click here is a good IR generalist but distinct optical coatings can really kick points up a notch.
Take note: A result of the current transform inside the Chinese exporting coverage, the exporting of Germanium optics is restrained and less than stringent supervision. You should inquire us if you want to order the Germanium Lenses
