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.
