Resolve Optics has released its Model 207 motorised miniature zoom lens. Based on this model, the company is able to offer instrument manufacturers and systems integrators development and supply of custom zoom lenses combining compactness and high performance.
Measuring 50 x 34 x 31mm, the Model 207 lens was designed for use with single chip 1/2- and 1/3-inch CCTV cameras. The Model 207 can focus on an object at infinity right down to an object positioned just 35mm in front of the lens. At the same time, and at any object distance, the image stays in focus throughout the zoom range. The use of the lens at such close object distances opens the door to a range of macro applications, because it allows an object to be shown at a very enlarged size on a TV monitor. High resolution focus tracking of images, macro performance and excellent bore sight accuracy has enabled the miniature zoom lens range to offer high performance.
