Terahertz (THz) wave refers to the electromagnetic wave whose frequency is in the range of 0.1 ~ 10 THz (wavelength is 3000 ~ 30 μ m). It coincides with millimeter wave in long band and infrared light in short band. It is the transition region from macroscopic classical theory to microscopic quantum theory, and also from electronics to photonics. It is called "THz gap" of electromagnetic spectrum. Terahertz lens is widely used in terahertz imaging.
The flat lens is one of the most commonly used optical elements, and is the simplest and the only optical element to be perfect. It can be used as a window, can also be used as a mirror, we provide a variety of materials, uncoated high-precision optical plane, the customer can also customize the size and coating. Please consult customer service price.
Spherical lens refers to both the inner and outer surfaces of the lens, or a spherical surface, and the other half is a planar optical element. We provide uncoated high-precision spherical lenses, customers can also customize the size and coating. Please consult customer service price.
Cylindrical lens is an aspherical lens, which can effectively reduce spherical aberration and chromatic aberration. With one-dimensional amplification function. We provide uncoated high precision optical cylinders of various materials, customers can also customize the size and coating. Please consult customer service price.
The aspherical lens has a better radius of curvature, which can maintain good aberration correction to obtain the desired performance. The application of aspheric lens brings excellent sharpness and higher resolution, and has a good application in miniaturization of lens. We provide high precision optical germanium, zinc selenide material coating of the aspheric surface, the customer can also be customized size and coating. Please consult customer service price.
Fixed focus lens is a lens with only a fixed focal length, only one focal length, or only one field of view. It is characterized by high speed and stable image quality. We provide high quality and high precision in the long wave lens, customers can also be customized size, detailed price please contact customer service.
Zoom lens is in a certain range can change the focal length, so as to get the different width of the field of view. The zoom lens can change the shooting range without changing the shooting distance. We provide high - quality, high - speed, long - wave manual zoom lens, electric zoom lens, continuous zoom lens, the customer can also be customized size, detailed price please contact customer service.
The medium long wave dual field of view optical lens has two field of view, which can realize the large field of view target search and small field of view tracking. In the military, plays an irreplaceable role. Compared with the continuous zoom infrared optical system, the system is more compact and easy to use. We provide high quality, medium and long wave dual field of view lens, customers can also be customized size, detailed price please contact customer service.
Medical non-contact is a temperature measuring lens, the temperature measurement accuracy is ± 0.1 ℃. To help the epidemic prevention and control, we provide customers with high-precision temperature measurement lens with focal length of 5-25 (mm).
