Zhejiang ULIRVISION Technology Co., Ltd. offers a wide range of range of infrared lens for china infrared camera. Below are our featured ir zoom lens and key factors need to consider for choosing infrared camera lens .
Optical System for Thermal Camera Lens
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.
2. Mechanical compensation zoom system: It means that each movement component is relatively complex and different corresponding movement according to different motion laws, and finally achieves the purpose of preventing image surface movement. Mechanically compensated zoom lens: one set of lenses makes a linear movement (known as a zoom group) to change the focal length, and the other set of lenses (commonly called the compensation set) makes a small amount of nonlinear motion to compensate for the image plane displacement to achieve optical system zooming. The image position is stable. |
