TPX window for Thz optics
Optical window made of Polymethyl pentene (PMP)
Material : TPX / Polymethyl pentene (PMP) is a polymer used in optics for its good transmission properties from UV (250nm) to THz. TPX/PMP has also a very low density (0.833 g/cm3), a low refractive index of 1.462 and good heat and chemical resistance.
Manufacturing process : mechanical cutting and polishing of optical windows. TPX/PMP like other optical plastics can also be injected.
Dimensions: Diameter 31.75mm, thickness 2mm, tolerance +/- 0.2mm
Shape : round flat window
Aspect : 60/40, both surface polished
Optical treatment : none
Usage : Terahertz optical applications, Thz lasers
Packaging : individual package, protected in optical paper
