自动焦距仪

镜头焦距测试图（72扇形星）反射率TE120_ATE120测试图被设计用于：相机镜头调整检测后焦距使用低透射滤光片和低水平照明以确保相机在光圈打开的位置没有过度调节。a）光学聚焦：调整变焦镜头的焦距到最大焦距。b）后焦距（镜头）：通过调节机械地调节镜头螺丝调整焦距到最短焦距，然后交替优化a）。c）后焦距（拾取管）：如果焦点在不同信道的最大和最短焦距变化，个别的拾取管必须机械的调整光轴。1、选择白色通信道。设置光学聚焦在最大焦距。调节W-通道拾取管的最短焦距和发射焦点达到最佳聚焦。必要时交替优化调节光学聚焦。2、调整红色和蓝色拾取管的不变焦距和最短焦距，直到最佳聚焦的实现。图像对焦（对焦调整）通过后焦距的调整得以在全焦段（放大）和恒定的距离对象。扇形星的外直径是一个分辨率测试图，这个扇形星的分辨率是50.5线，即0.65MHz（625线）或0.64MHz（525线）。这个扇形星有一个不确定的部分直接是为直径的1%。The TE121 test chart is designed for?adjustment of camera lenses?checking back focal distanceWith the aid of a low transmission filter and by means of low level lighting make sure that the camera is not over modulated with the aperture in the open position.a)Optical focus: Adjust focus of zoom lens at greatest focal length.b)Back focal distance (lens): Adjust focus at shortest focal length by regulating lens mechanically with adjustment screw and optimize alternatively with a).c)Back focal distance (pick-up tubes): If focus varies from channel to channel between greatest and shortest focal length, the individual pick-up tubes must be adjusted mechanically in the optical axis. 1.Select white channel. Set optical focus at greatest focal length. With shortest focal length and divergent focus adjust the pick-up tube in W-channel until optimum focus is achieved. If necessary optimize by alternating with optical focus adjustment. 2.With unchanged optical focus adjustment and shortest focal length adjust the red and blue pick- up tube until optimum focus is achieved. Image focus (focus adjustment) is maintained at all focal lengths (zoom-in) and constant distance from object by means of back focal distance adjustment.At the outer diameter of the sector star there is a resolution of the sector star there is a resolution of 50.5 lines, i.e. 0.65 MHz (625 lines) or 0.64 MHz (525 lines). The unresolved center of the star has a diameter of 1% of the outer diameter.1、厂家货源正品厂官方直售，公司生产周期短，出厂严格检测，货品品质保障，可通过国家计量院计量。2、关于尺码机身和包装尺寸为手动测量，由于测量工具和测量方法不同的因素，会存在1cm误差，但是不用影响运输和使用。3、关于颜色本店产品都是实拍图片，但是由于不同显示器分辨不同以及色温和对比度差异有所不同。4、关于客服可以通过阿里旺旺随时联系我们，如果旺旺回复不及时，也可以拨打我们的热线电话 陈工：13310057372（技术与销售一体，直达客户需求）5、关于售后我们将提供完整的售后服务，包括15天退货，正品保证，交期保障等等。6、关于发货本店根据货物及客户需求，尽可能选择快捷方便的物流运输服务，一般情况发顺丰快递！
