Aperture Area Meter: F Number Tester SMD-81T2
Measuring the aperture diameter areas of various camera lenses. The SENS sensitivity that can be calibrated and registered supports measurements for 4 series zoom lenses and others. Custom specifications can be ordered.
This device measures the aperture diameter area of cameras and interchangeable lenses. - Aperture diameter at the time of synchronization contact - Maximum aperture diameter at the time of shutter release - Open aperture diameter - Aperture diameter at the timing of the start of aperture operation synchronization It displays the aperture error amount (●EV) compared to the reference diameter as measurement results. The SENS sensitivity, which can be calibrated and registered with a standard lens or reference camera, has four series and supports measurements for zoom lenses and others. The measurement unit can be installed vertically as well as horizontally (the angle position of the display unit can be adjusted). It allows posture difference measurements with two types of optical axes depending on the installation method. Equipped with a communication interface (RS-232C). It enables external output of measurement data and external control of the tester.
