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。
Beam handling is required in many THz applications. Currently it is carried out by parabolic mirrors and refractive optics. However diffractive optics opens up new, basically different opportunities of beam handling since it allows realizing spatial transformation of THz beam.
To satisfy needs in diffractive optics for THz range we have developed calculation methods and manufacturing technology of the following diffractive optical elements (DOE):
- THz Fresnel lenses,
- THz beam dividers.
