USAF 1951 Test Target On Glass

Description

USAF1951 High Resolution Calibration Targets

Resolution targets are very important when evaluating or calibrating an imaging system's performance or image quality. To make sure the accuracy of resolution, contrast, modulation transfer function (MTF), depth of field (DOF), and distortion; USAF195 calibration target is one of the resolution test targets to identify resolution of an imaging system or optical system.There are positive and negative patterns available.

The USAF1951 pattern designed according to the American military standard MIL-STD-150A,so we sometimes call it air force resolution target, its different resolution units use the corresponding group and unit marks, and the corresponding resolution of each unit can be obtained by looking up the table.The glass USAF test target is one of the most popular optical test targets.

Positive test Targets: composed of a chrome pattern etched on soda lime glass or quartz glass, with a clear glass substrate background,it is reflective and transparency., useful for front light illumination source and general applications.

Negative Test Targets: Negative target uses the chrome to cover the substrate, leaving the pattern itself clear, the high contrast between the pattern and the background makes this target ideal for reflective applications. and works well in back light illumination source and highly illuminated applications.

Application:

USAF1951 positive resolution test targets are recommended for quality control of vision systems and testing instruments. USAF1951 positive targets can be used on the high power microscope head.

It shall be packed in boxes with a corresponding table of resolution values. This product complies with MIL-S-150A.
