MTF ImageMaster Afocal measurement station

As its name suggests, this system is designed for image quality testing, MTF, of afocal systems such as telescopes or spotting scopes. It performs precise measurements of a wide range of parameters, such as MTF and magnification for telescopes and spotting scopes. Options and sample holders are available for measuring binoculars and spotting scopes.

The measuring process can be manual or fully automated. The collimator can be focused for specific measurements such as parallax (free distance).

Parameters measured :

• MTF on-axis and off-axis
• Magnification
• Distortion
• Lateral chromatic aberration
• Longitudinal chromatic aberration
• Astigmatism
• Field curvature
• Parallax (reticle alignment control)
• Field of view; objective and subjective (optional)
• Others on request
