Long-wave infrared refers to infrared rays with wavelengths between 8 and 15 micrometers. The human eye cannot directly perceive light in this wavelength range, but through long-wave infrared lenses, we can capture the infrared radiation emitted by objects. Read More

Generally speaking, a lens with a focal length of 18-35 mm can be regarded as a wide-angle lens​. The basic characteristics of wide-angle lens are large lens angle and wide field of vision. The range of scenery observed from a certain viewpoint is far greater than that seen by the human eye at the same viewpoint. It can emphasize the perspective effect of the picture, be good at rendering the foreground, and express the sense of distance and proximity of the scene, which is conducive to enhancing the attractiveness of the picture.

Both are variable-focus lenses with variable focal length and adjustable sharpness. But there are a few fundamental differences:A, structurally, the continuous zoom lens has two sets of adjustable lenses, which are used to adjust the focal length and sharpness. Dual field lenses have only one set of Read More

1. Zinc selenide (ZnSe)CVD zinc selenide (ZnSe) is a chemically inert material with high purity, strong environmental adaptability, and easy processing. It has low light transmission loss and good light transmission performance. It is the material of choice for high power CO2 laser optical component Read More

A long-wave infrared thermal imager is an imaging instrument that uses the principle of thermal radiation to detect the temperature distribution of an object and generate a corresponding infrared image. It has a wide range of applications in many fields, such as industry, military, medical and so on Read More

In conclusion, infrared lenses are widely used in security for several compelling reasons. Their excellent night vision capability, resistance to bad weather, wide field of view, ability to detect hidden objects and people, and seamless integration with other security systems make them an essential tool in ensuring the safety and security of our homes, businesses, and public spaces. As technology continues to advance, we can expect infrared lenses to become even more sophisticated and play an even more crucial role in the field of security. Read More
