Our aspheric lenses have a more elaborate entrance. The curvature step by step modifications as you progress from the center of the lens out to the sting. Our aspheric Ge lenses are most often used to reduce spherical aberration within an optical program.

Ge is additionally appealing for its small optical dispersion and therefore extremely reduced chromatic dispersion in it’s transmission spectrum.

Anything more than 100ºC just isn't advisable. By the point it reaches 200ºC it is almost opaque in the slightest degree wavelengths. If you want a significant temperature window, you’re improved suited to keep on with a cloth like MgF2, YAG or our aged Close friend sapphire.

When not in use, we recommend storing your germanium windows wrapped in lens tissue with humidity below 30% and in between 15 and twenty fiveºC. When germanium is very rough stuff, they are The best problems that could prolong the everyday living of the window.

Hi, I'm your virtual assistant, I'll do my easiest to assist you navigate all items Fluke connected. You may talk to me just about anything! I am new and may possibly generate a number of problems.

Just one very common circumstance we see germanium utilized is within substantial and reduced velocity wind tunnels for jet propulsion studies. Ordinarily, these windows are much bigger than stock configurations achieving measurements in excessive of one hundred ninety-200mm.

Germanium is actually a high index content that is used to manufacture Attenuated Complete Reflection (ATR) prisms for spectroscopy. Its refractive index is these types of that Germanium would make a good pure 50% beamsplitter with no need to have for coatings.

This high-density window features a thermal escape which makes the transmission cut down since optical germanium lens the temperature of your window raises.

I consent that JENOPTIK AG or even the Jenoptik Group corporation responsible for my ask for may well system my e-mail tackle and my other own knowledge entered during the Call form in order to contact me by e-mail, telephone or in any other case and send out me info on services and products offered by the Jenoptik Group.

Optical precision is important to satisfy distinct necessities relevant to precision, surface area top quality, and All round optical efficiency.
