TE281

Flare target according to ISO 18844

te281 imagete281 image

The TE281 Flare test chart is designed to determine the amount of lens flare, which is added to an image by a camera.

Flare arises from reflections of light at every surface inside of the lens and camera. It reduces the image quality by producing a diffuse veil over the image field and thus leads to a loss of contrast.

The super black holes of the TE281 generate the lowest possible black level because they absorb a high proportion of light. But this black level will be affected (raised) by flare.

The iQ-Analyzer’s Flare module compares the white level and the black level in the test image. The software calculates the proportion of scattered light. This delivers the loss of contrast caused by scattering light.

Technical information

The test chart is available in size A1066. The relevant area used for the analysis has a size of 750 x 500 mm.

Recesses are arranged on this reflective test chart on the two diagonals, against which 17 light traps (super black holes) can be attached from the backside. Testers can remove the robust light traps easily during assembly, chart changes or for storage.

Standard illumination systems like Hedler halogen lamps are suitable for the illumination.

The analysis can be made using the iQ-Analyzer’s Flare module (from version 6.1).

Chart sizes

The test charts are available in the sizes listed below. However, for technical reasons, some charts cannot be manufactured in all sizes. Please do not hesitate to ask for additional information.

During production, specific regions of test charts are measured to qualify the production process or to create individual reference data accompanying a test chart additionally. Measured regions can be color or gray tones.

The measurement devices are calibrated regularly and proven before use. You can find further information in our reference data accuracy sheet.
