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.
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).
Telecentric scanning lens is a specially designed scanning lens. By making the exit pupil of the lens infinitely far away in the image space, the main light of the focused beam is perpendicular to the focal plane at any field angle. The telecentric scanning lens has special advantages in reducing the distortion of the focusing spot and drilling angle, and is suitable for high-precision laser applications, with the wave bands covering 355nm, 532nm and 1064nm, It has the characteristics of high damage threshold.
Prime lens refers to a lens with a fixed focal length, only one focal segment, or only one field of view. The focus lens has no zoom function. Its characteristics are fast focusing speed and stable imaging quality. We provide high-quality and high-precision medium and long wave lens, customers can also customize the size, please consult customer service for detailed price.
