SPHERICAL LENSES CHARTS
250 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 250 pairs of lines printing on the sensor, ﬁlming the entire chart in full frame (Yotta chart). No sensor can reach that deﬁnition so far !
Find circular targets with different sizes all over the chart. The numbers in the circular targets, in twentieth of a millimeter, express the number of pairs of lines printed on 1 millimeter. Numbers go from 4 to 55.
Find linear targets with different sizes all over the chart. The numbers in the linear targets, in twentieth of a millimeter, express the number of pairs of lines printed on 1 millimeter. Numbers go from 4 to 55.
Find many Siemens charts all over the board to get an easy and quick sharpness calibration.
No need to remove the chart from the wall to make the frame leader test. The main frame leaders are on the chart : 1.33 – 1.78 – 1.89 – 2.00 – 2.39.
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.
Magnetic neutral grey
Add a 18% neutral grey using the dedicated magnetic area.
Magnetic grey scale and grey gradation
2 cross grey scales with 21 steps and 2 cross grey gradation can also be magnet on the chart.
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.
