SKU: SP-PH-MULTI

The SFRplus Photographic Multi-Size target is ideal for a variety of specialized testing applications. This chart is of particular interest for endoscope and medical device manufacturers, as the always-on, embedded light sources of these instruments often prevents the use of a high-resolution transmissive target.

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. Some of these advantages are less wasted area, the ability to produce a map of sharpness over the sensor surface, better measurement accuracy, and full support for automated testing.
