Anamorphic Lenses Chart
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 !
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.
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?
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.
Our charts are fully protected by an aluminium frame. Light and rigid, it helps the manipulation during the tests and avoid bending over time.
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.
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.
Centering aid mirror
Here is a very smart and useful aid to win time on your camera test ! The mirror helps to place the chart perfectly parallel to the image plan in a matter of seconds.
You have the possibility to add a very useful bubble level on the top of the chart.
