This transmissive (backlit) SFRplus test chart can be used with the Imatest SFRplus module to measure MTF, lateral chromatic aberration, distortion, and tonal response. The SFRplus module features fully automated region-of-interest detection.
The SFRplus chart offers significant advantages over commonly used charts such as the ISO 12233 chart, including
This chart has an active chart area of 48.3 cm x 26.81 cm (19 in x 10.56 in) in a total film size of 30.48 cm x 50.8 cm (12 in x 20 in). Bar-to-bar height is 252 mm (9.92 in).
This chart is produced with a high-precision, black and white, LVT film recording process for the best possible density range, low noise, and fine detail. The edges have an MTF50 >= 10 cycles/mm, which is about 2 times better than the best inkjet charts. For more information please take a look at our transmissive chart quality comparison! The large patterns are fine enough to produce good results with up to 30 megapixel cameras.
With 12 rigorous quality inspection processes in place, we ensure a high yield rate of up to 98% for batch processed precision parts.
FAQs About SFRPlus Test Charts
D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries.
You can choose a colorimters depending on the substrate you are measuring the color of, whether it is opaque, translucent or transparent. In short, you can consider the following factors for choosing the right 3NH colorimeter for your needs: Sample Opacity, Physical Form, Optical Properties needed, Measurement Methods required, Scales and Indices needed, Instrument Standards Conformance (ASTM/ISO/Other), Instrument Geometry, Instrument Performance, Location (laboratory, portability, in-process) and Sample Handling requirements.
By systematically addressing these factors, you can select a colorimeter that optimizes accuracy, efficiency, and value for your specific application.Learn more from our ultimate guide on colorimeter selection. If unsure, consult the 3NH manufacturer for personalized recommendations based on your sample and workflow.
