TPX Lens
Product Introduction：
TPX is the lightest among all known polymers. It is transparent to ultraviolet, visible and THZ wavelengths. Of course, it can also be collimated using a He-Ne laser. The refractive index of this polymer is approximately 1.46, and it has little relation to the wavelength. TPX materials are often used to manufacture optical components for the terahertz band. TPX lenses and TPX window plates are the most common types among them.
The refractive indices of TPX material from visible light to terahertz wavelengths are as follows. We measured and calculated at several typical frequency points.
λ, µm | n |
0.633 | 1.463 |
24 | 1.4568 |
60 | 1.4559 |
300 | 1.46 |
667 | 1.46 |
1000 | 1.4650 |
3191 | 1.466 |
In addition, the TPX lens and TPX window have extremely low transmission loss for mm waves. They have excellent thermal resistance and can resist the corrosion of some commercial chemicals.
The spectral transmittance curves of TPX lenses and TPX window sheets
The transmittance curve of a 2mm-thick TPX window sheet in the terahertz frequency range
The transmittance curve of a 2mm-thick terahertz window sheet in the near-infrared and mid-infrared wavelength bands
The transmittance curves of a 2mm-thick TPX window sheet in the ultraviolet, visible light, and near-infrared wavelength ranges
The transmittance rates of TPX window sheets and TPX lenses are significantly superior to those of the lenses and window sheets made of Picarin and HDPE materials, as shown in the transmission rate curves：
