Product Introduction

TPX is the lightest among all known polymers. It is transparent to the ultraviolet, visible, and THZ bands. Of course, He Ne laser can be used for collimation. The refractive index of the polymer is about 1.46, which is not closely related to wavelength. TPX materials are often used to fabricate optical components in the terahertz band. TPX lenses and TPX windows are the most common among them.

The refractive index of TPX material from visible light to terahertz wave points is as follows. We selected several typical frequency points for measurement and calculation

In addition, TPX lenses and TPX windows have very low transmission losses for millimeter waves. It has excellent thermal resistance and can resist corrosion from some commercial chemicals.
