    High-Resistivity Silicon Lenses High-resitivity silicon lenses transmit more than 50% of terahertz radiation in the 501000µm spectral region when the lens thickness is less than 0.5mm. As can be seen from the plot, HRFZ-Si has superior transmission properties due to its high resistance and lack of absorption lines in this spectral region.
