Tydex公司专业订制生产THz光学镜片，可以提供太赫兹专用离轴抛物镜、滤波片、偏振片、窗片、透镜、棱镜、波片、分束片、反射镜和菲涅尔透镜等，同时还提供太赫兹衰减器、太赫兹宽带相位变换器。
For operation in FIR and THz regions we supply polyethylene polarizers designed to polarize radiation from 7 microns to MM waves. They are the sort of diffraction gratings and operate in transmission. The polarizer grating is made by forming grooves of a triangle profile on the substrate and subsequent deposition of a metal coating (aluminum) on one of the groove facets.
Applications
THz microscopy
Molecular orientation studies of crystal and polymer films
Imaging
Sensors and detectors
FTIR spectroscopy
THz spectroscopy studies
Features
Used in extremely wide wavelength range from MIR (7 μm) to THz ( 3 mm and even more)
Substrate is high density polyethylene (HDPE)
High FIR transmission
High degree of polarization
Polarizers are supplied in holders (protective ring with marked grid direction)
Advantages of polyethylene grid polarizers compared to free-standing wire grid polarizers:
Lower cost
Possibility to use one polarizer for the wide wavelength range
