1. Optical compensation zoom system: When several sets of lenses are used for zooming and compensating in the zoom objective lens, the movement of each lens group is performed at the same direction, so that it is only necessary to connect the lens groups together in a simple mechanical structure for linear operation. Since the optical compensation zoom system cannot completely compensate for the image plane displacement, the moving group must be moved to a certain special position to obtain a stable and clear image surface, and the focal length is difficult to achieve continuous change, but several discrete values, so the usage is limited. However, it simplifies the mechanical structure and is beneficial to control the accuracy of the optical axis; and only uses a set of electromechanical control systems to achieve zooming and focusing, thereby reducing the cost and weight of the system, but the design difficulty is relatively large.

ULIRVISION infrared zoom lens has coating waterproof rating IP67, and the working temperature from -40℃~60℃, the focal length various from 25mm to 225mm; rear working distance from 8 to 14. Want more details about our athermalized lens? Come download our pdf and get a free quotation!

1. Infrared gas leakage camera Most of the gases have characteristic absorption peaks in the mid-infrared region, and the concentration of a certain gas can be determined by detecting the absorption of the characteristic absorption peak position. This sensor has been successfully used for the detection of gases such as carbon dioxide, methane and sulfur hexafluoride.

We all know about induction base pressure cookers and induction cooktops, but hardly know how that works? The cooktops heat up the cooking vessels with induction heating, instead of infrared heating or gas flames of a traditional cooking stove.

TC800PTZ is a photoelectric products specially designed for special applications. Some of the functions of TC800PTZ are as follows: Integrating uncooled infrared thermal imaging and high-definition visible light camera, laser illuminator or laser ranging module are optional, higher sensitivity than conventional products, daytime optical filtering and DSP image processing. Naturally, this device can enhance image detail in mist, water vapor, and dust environments, and it is able to show you more exquisite picture quality. The whole camera is made of super strong aluminum alloy shell, IP66 protection, rain proof and dust proof, which can adapt to all kinds of harsh environment. If you need to long distance observe under various weather conditions of pitch duck, fog and rain, your choice of this product is correct.

TC900PTZ integrates cooling infrared thermal imaging and high-definition optical camera. It can be equipped with laser illuminator or laser range finder, GPS, radar, electronic compass and other modules. High precision MEMS gyroscope ensures stable image output in wind and waves. Radar tracking and rotation prompt function can help you realize the function of tracking the target in real time. Protection class IP66 makes it suitable for use in harsh environment. The body is made of high-strength aluminum alloy, coated with three anti paint which is resistant to seawater corrosion, spherical body, and low wind resistance.
