Details

TPX lens, also known as terahertz lens, is made of TPX (poly (4-methylpentene) material and is used as a lens in the terahertz band with a designed wavelength of 300 μ m. Terahertz waves generally refer to electromagnetic waves ranging from 0.1 THz to 10 THz, with a wavelength of 0.03 mm to 3 mm, between microwave and infrared, and are commonly used for material identification or non-destructive testing.
Guangtan Intelligent has launched TPX lenses with diameters of 25mm and 38mm, covering focal lengths of 35mm, 50mm, 100mm, and 200mm. This type of product is mainly used for focusing and collimation in the terahertz band in optical systems, and is widely integrated in terahertz spectrometers, terahertz imaging systems, terahertz research and related fields.
