High-Resistance Silicon Wedge Lens, THz Lens
The conical lens, or cone lens, launched by Shanghai Tera photoelectric Technology, is used to transform a Gaussian beam into a Bessel beam. The high-resistance silicon conical lens can focus the incident beam onto a straight line composed of a group of points along the optical axis. This line forms an equal-width ring, whose diameter increases as the distance from the optical element increases.
