Sad to say Germanium is wise to significant temperature with degradation of its optical Homes over a hundred°C.
If significant transmission is the only real thing to consider, you’d be ideal served to double coat your Home windows with BBAR above unique wavelength ranges and you will see transmissions each of the way nearly ninety nine%. Now we’re speaking!
Jenoptik manufactures hybrid parts in optical substance for infrared programs. They are ideal for infrared aim lenses and devices, and also for picture seize, focus on detection and in infrared camera engineering. It is possible to Choose between concave, convex, plane, spherical and aspherical surfaces. Information Sheet

It's the special hardness of germanium that provides it its distinctive ruggedness; Ge contains a Knoop hardness of 780. It's a significant density materials, at five.33 g/cm3, and allowances should be manufactured for this weight Should you be building a body weight delicate technique.
Novotech is a worldwide provider of evaporation quality Germanium. We assist IR coating businesses and the fiber optics field with their product desires.
We develop and manufacture optical parts in the very best quality that you could use in a number of fields of application, from laser substance processing to biotechnology, healthcare technological know-how, defense and stability as well as the semiconductor sector.
Aspherical germanium lenses : built and used for Increased optical properties and for applications that want weight preserving. Germanium could be diamond became substantial area quality aspheres.
Germanium can be a high index materials that is definitely utilized to manufacture Attenuated Total Reflection (ATR) prisms for website spectroscopy. Its refractive index is this sort of that Germanium would make a successful all-natural 50% beamsplitter without the will need for coatings.
