Millimeter-Wave and Terahertz Optics

Many common plastic materials can be used to make useful MMW and THz optical components. Lenses can be machined on a lathe, and the exact desired hyperbolic figure can be obtained to avoid spherical 

The examples given in this section are just a few of the many applications of optical techniques in the MMW and THz bands, ft would not be possible to build many systems in these bands without using optical techniques.
