Resolution Test Targets

Resolution is an imaging system's ability to distinguish object detail. In case of without consideration of diffraction, the resolution of optical system is closely related to its aberration, hence the resolution is often the key indicator to evaluate the imaging quality of optical systems.

Based on our years of experience and high technology accumulated from imaging quality evaluation work, herein we successfully launched resolution test target series products. Whether you need to test for resolution, contrast, depth of field or distortion, we offer a large selection of test targets.
