Digital Imaging
Our activities are focused on digital cameras test charts and scanners targets.
We produce wide assortment of both transmissive and reflective charts for measuring
limiting resolution / MTF
opto-electronic conversion function / dynamic range
colour rendition / ICC profiling
Actual measured data: Many of our test charts come together with actual measured data.
Density, Transmission/Reflection coefficients, Lightness, RGB levels, spectral curves.
Our camera test charts are only rarely glossy.
Even 160:1 luminance ratio charts are easy to glareless illuminate.
Our assortment is rapidly changing according to our client´s needs.
Please, ask us for our actual size, material and precision possibilities.
