In this revision the surface type of the test charts has been changed from Semi-Gloss/Luster to Matte, as a measure to reduce specular reflection.Charts are black and white, including a focus star, 20 patch step chart, and include 10:1 as well as 2:1 contrast ratios.As shown on our blog, these charts are first mentioned in Version 5.0 of the Skype™ Hardware Certification Specification.Skype™ is a registered trademark of Skype Limited.Lighting Setup for ITDR-36As written in the specification, "This chart needs an uniform light emitting surface below the chart, such as a dedicated light box." For this purpose we recommend the GL-16E Lightbox Viewer. This lightbox provides even illumination and features a high frequency ballast to eliminate flicker.Ink Jet Chart ResolutionThis chart, and all our ink jet printed charts have an approximate MTF50 of 5 cycles/mm. Please keep this in mind when choosing the size of chart. Using a chart that is too small with a high-resolution sensor can result in the MTF of the chart degrading the measured MTF of the camera system.1、厂家货源正品官方直售,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:1331000468 (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!
