| titleOfInvention | Wide-spectrum large-view-field terahertz wave lens |
| abstract | The utility model provides a wide spectrum large field of view terahertz wave camera lens, includes along the optical axis direction from the thing side to the image side first biconvex lens, diaphragm, second biconvex lens, plano-convex lens, biconcave lens and the detector screening glass that sets gradually, first biconvex lens, second biconvex lens and plano-convex lens are positive focal power, biconcave lens is negative focal power. The lens is simple in structure, all the lenses are made of TPX materials, cost is greatly reduced, and weight of the system is reduced. The terahertz wave imaging objective has the characteristics of large aperture, large field of view and high resolution, and can obtain excellent imaging quality in low light and 0.2-4 THz broadband, so that the object which can be detected by the objective is more diversified, the application range is greatly expanded, and the terahertz wave imaging objective has great application prospect in the field of terahertz wave imaging optics. |
