Infrared continuous zoom lens with external tension spring

Abstract

1. Name of the product in this design: Infrared continuous zoom lens with external tension spring. 2. Purpose of this design: To capture the infrared radiation of objects and achieve clear imaging of targets at different distances through the lens's electric continuous zoom function; the external tension spring is used to eliminate mechanical gaps during the zoom process, ensuring smooth movement of the zoom cam during lens zoom. 3. The key design feature of this product is its shape. 4. The image or photograph that best illustrates the design's key points: a 3D model.
