Anamorphic Lenses Chart

All the P.A.T. camera sharpness charts have the indispensable tools and aid to realize the best camera test. Cameras that become increasingly technical and sensitive literally shorter the lenght of your day in test. Our charts are made to let you win time, confort and efficiency. You don’t have to take the chart off the wall. Everything you need is here.
Also, the P.A.T. charts have a sleek and elegant design. All the tools serve technology but materials and designs that compose the charts have been thought to emphasize your spaces. Most of all, your printed logo on each charts makes them fully yours in your company premises. Useful and beautiful chart to create beauty. Our main concern is ultimately the same as yours : create beautiful pictures to make beautiful movies.
But that does not end what makes the Prêt à Tourner Charts so unique. We offer you the possibility to get a real technological head start on the test of your cameras and lenses. As a matter of fact, we found the way to print the very small to allow you printing 250 pairs of lines per millimeter on your sensor, filming the entire chart in full frame. We are the first one to reach that impressive high level of printing on formats 150 cm width. Today, no sensor is accurate enough to reach this definition.


200 pairs of lines per millimeter

The unrivalled printing quality for that kind of large formats offers for the first time the possibility to reach the 200 pairs of lines printing on the sensor. No sensor can reach that definition so far !

Anamorphosis x2

Inserted into a 2.39 format frame, the Peta chart is specially designed for calibrating anamorphic lenses and anamorphic zooms and allows for the verifying a perfect x2 anamorphosis.


The arrangement of the targets allows a very precise analysis of the anamorphosis of the lens. Find uniformly arranged black and white cross lines : circular and linear, horizontal, vertical and diagonal.

Geometric deformations

The chart allows the materialization of geometric deformations through the tests of the “plumb line” and the “checkerboard”. In addition, the checkerboard consists of 18% neutral grey areas. Why deprive yourself?

Magnetic support

The entire support of the charts is magnetized to help the manipulation, using a metallic wall and even magnetic paint. This magnetic support at the back is your assurance of the immediate flatness of the chart.

Aluminium corner

Our charts are fully protected by an aluminium frame. Light and rigid, it helps the manipulation during the tests and avoid bending over time.

Mat coating

The mat coating of the charts protects the printed ink and avoids any light reflexion that could disturb the test. Most of all, you can write on it !

The magnetic customization area let you make the chart fully yours.

Magnetic annotation areas

Write the useful and indispensable technical informations on the magnetic writable and erasable annotations areas. This tool protects the entire chart against time.

Optical wedge scale

The optical wedge scale allows to evaluate and quantify the sharpness of spherical and anamorpgic lenses. It gives a mathematical data of the sharpness to help the technical exchanges between users, like camera assistants, and camera technicians.

Neutral grey

The checkerboard consists of 18% neutral grey areas.

Color Checker Classic ®

Digital cameras may require some color test. You have the possibility to add a ColorChecker Classic® using the Velcro® pads in the middle of the chart without removing it from the wall.
