It shows asymmetrically arranged one zone plate ranging from 0 to 600 c/ph and two zone plate sectors with their centers located in the left corners. The gore-shaped gaps are gray.TE188TE188 16:9Color Rendition Chart (X-Rite ColorChecker)The TE188 was designed with respect of the well- known 'ColorChecker'. Used in photography, film and TV, the chart consists of 18 color patches and a 6-step gray scale.TE241 16:9OECF/Noise Chart with 20 gray patches 10000:1 (ISO 14524, ISO 15739) The TE241 is designed to measure the characteristic curve of digital cameras. It is an extended OECF chart and has 20 patches and a contrast range of 10000:1 or if needed 100000:1.TE244IE Pattern ResolutionThe TE244 is designed to check aliasing behavior of digital cameras.TE245IE Landolt Circle ResolutionThe TE245 is designed to make a visual resolution analysis of digital cameras. It contains Landolt circles in different sizes.TE248 16:9Distortion GridThe TE248 is designed to measure disortion of digital cameras. It contains a fine grid of black lines on white background.TE251 16:9Distortion and Chromatic Aberration, CrossesThe TE251 is designed to measure disortion of digital cameras. It contains black crosses on white background.TE253Modulated Sinusoidal Siemens StarThe TE253 is designed for checking resolution. The chart contains a radially sine modulated Siemens star in the center of the image, gray patches and black squares with a small white square in it.TE253 9xModulated Sinusoidal Siemens Star Set of 9 stars arranged in 3 columnsThe TE253 is designed for checking resolution. The chart contains nine radially sine modulated Siemens stars, gray patches and black squares with a small white square in it, slanted edges and white noise patches.TE255Diffusor Plate to measure vignettingThe TE255 is designed to measure shading/vignetting of a digital camera. It is a very precise milk glass palte which is used in combination with an integration sphere or a light box.TE260 16:9Dot ChartThe 'dot' chart consists of two different charts on the front side and the back side. One of them has 31 lines of dots and the other 15 lines of dots. They can be used to determine distortion and chromatic aberration. TE261 16:9Slanted EdgesThis target has a tilted chequerboard in the background and five low contrast slanted edges together with surrounding gray patches in the front. It is used to determine the SFR of digital capture devices and is our default chart in combination with the AF-Box and STEVE.TE264 16:9OECF 20 ISO 14524 / 15739 revisionThe former OECF chart contains 12 or 20 gray patches in a circular order and three different patterns in the center of the chart. The actual version of the OECF chart skips the center patches due to sometimes occurring straylight. This chart is also offered as TE264X where the 20 gray patches are not rasterized like in the standard version of the chart but done with nearly no structure on a very fine grained film.TE265Dead LeavesThis chart contains so called dead leaves (in this case circles) structure. The structure is made of circles in all sizes and gray levels. A fourier transform of an image of this structure taken with a camera provides the power spectrum that the camera is able to reproduce.
