Customized Ge Optical Right Angle Prism

What is a Ge Prism?

The Ge prism is a high-precision optical component which is often used in infrared (IR) applications.

The refractive index of germanium is 4.0 and its critical angle is only 14.5 degrees. Therefore, it is good for the refraction and propagation of light.

With excellent transmission in the 2–14 µm wavelength range and a high refractive index (~4.0), people often use them in infrared imaging, spectroscopy, thermal cameras, and laser systems.

And due to their outstanding durability and well optical performance, Germanium prisms are a preferred choice for IR optical designs.

People can choose AR coating or other coating according to their requirments.

 

Core advantages of the Ge prism

• Wide Infrared Transmission Range:

The Ge prism has good transmission. It is ideal for mid-IR and long-wave IR applications.

• High Refractive Index:

~4.0 at 10.6 µm, enabling compact optical designs.

• Well Surface Quality

The surface quality of the Ge prism is very well. It can make the light focusing better. Precision polishing techniques are made the prism surface accuracy better.

• Thermal Stability:

Beacuse of the features of the prism,  the Ge optical prism performs well in varying temperature environments.

The Germanium prism is renowned for their excellent thermal stability. And it maintains well optical performance across a wide range of operating temperatures.

It will be affected even under rapid temperature fluctuations. Therefore, it ensuresstable in both high-heat and low-temperature environments.
