What is a TPX Lens?
A TPX lens is a type of lens that is made of a plastic material called polymethylpentene (TPX). It is used for focusing or collimating terahertz (THz) radiation, which is a form of electromagnetic radiation with frequencies between 0.1 and 3 THz. THz radiation has applications in imaging, spectroscopy, security, communication and biomedical fields.
A TPX lens is needed because it has high transparency and low attenuation in the THz range, compared to other materials such as PTFE (Teflon) or silicon. It also has a low refractive index of about 1.46, which means it can bend light less than other materials and reduce aberrations. TPX is also lightweight and easy to handle.

Application of TPX Lens
TPX lens is used for focusing or collimating THz radiation, which has many potential applications in different fields. Here are some examples:
- Terahertz spectroscopy: This is a technique that uses THz radiation to probe the molecular structure and dynamics of various materials, such as drugs, polymers, explosives, gases, and biological molecules. TPX lens can be used to focus the THz beam onto a sample or a detector.
- Terahertz imaging: This is a technique that uses THz radiation to create images of objects that are opaque or hidden in other wavelengths, such as clothing, paper, wood, or plastic. TPX lens can be used to form an optical system that captures the THz image of an object.
- Terahertz communication: This is a technique that uses THz radiation to transmit data at very high speeds and bandwidths, beyond the current 5G wireless technology. TPX lens can be used to collimate or direct the THz signal between a transmitter and a receiver.
- Terahertz astronomy: This is a technique that uses THz radiation to observe celestial objects and phenomena that emit or absorb THz radiation, such as interstellar dust, star formation, black holes, and cosmic background radiation. TPX lens can be used to focus the THz radiation onto a telescope or a detector.
A simple setup of THz Application
The setup consists of a THz antenna, a TPX lens, and a post or a rail for alignment. The THz antenna converts an optical pulse into a THz pulse or vice versa. The TPX lens collimated the THz radiation from the antenna, which means it makes the rays parallel. The post or the rail holds the TPX lens near the antenna and allows for adjustment.
Here is a markdown representation of the setup:
THz Antenna <—-> TPX Lens <—-> Post or Rail
The <—-> symbol indicates the direction of the THz radiation and the alignment of the optical pulse. The TPX lens is placed at a distance equal to its effective focal length from the antenna.
