Diffuser Plate To Measure Vignetting The TE255 is designed to determine the shading/vignetting of a digital camera. The transparent chart provides a very neutral transmission. It can be used in combination with an integrating sphere or a light box.
Technical information
Transmission: 84% for 400 – 800 nm
The TE255 is now offered with a matt finish.
An analysis of the images, taken from this test chart, can be done using our iQ-Analyzer analysis software. The analysis will provide the following results:
Luminance shading (in f-stops, digital values and CIE-L)
Color shading (CIE-C, G-R and G-B; CIE-E_ab)
Visual noise
A spectrometer diffuser cap is included with the TE255. The diffuser cap ensures that the measurement by the spectrometer matches to the light emitted from the LE7.
The TE255 is supported by the iQ-Analyzer-X image evaluation software.
