Zeiss Siemens Star Test Chart Compact Prime CP.2 - For Adjusting Lens Back FocusAligns CP. The system functions by structuring the pathways of the chemical process. Set optical focus at greatest focal length. Brand Zeiss Zeiss 1849-755.pdf 20,00 + VAT Request lower price Interest form Designed to test and set the back focus on DSLR cameras, the Zeiss Siemens Star Test Chart is a professional lens chart that is particularly effective when swapping a Zeiss CP.2 cine lens mount from one type (i.e. The Siemens process is currently the de facto standard in the production of polysilicon. This system strives to improve upon this design as well as to create additional profit through an additional process reaction that utilizes the waste products of the Siemens. With shortest focal length and divergent focus adjust the pick-up tube in W-channel until optimum focus is achieved. MTF and image linearity functions are implemented in MTF.py and ImgLinearity.py.The MTF class takes a cropped image containing only a Siemens star chart, and the ImgLinearity class takes an X-Rite ColorChecker chart and utilizes the colorimetric data found here to create linearity plots for R, G, and B channels in an image. If necessary optimize by alternating with optical focus adjustment.Ģ、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.
