Shutter Lover

The Shutter Lover is a device specialized in the measurement of the travel time of shutter curtains.

Its design includes 3 LED used to enlight the 3 measurement points of the sensor in order to prevent any parallax error. That leads to an excellent accuracy, at up to 1/4000s.

The screen of the device displays the following informations

  • First and second curtain travel times
  • Shutter speed values at opening, center and closing points of the frame.

More detailed data values are streamed on the USB port and can be collected on a personal computer.

The sensor is 35mm format. An adapter is supplied for medium-format cameras.

Remote application

Verification of the accuracy of the tester

The accuracy of the tester has been tested using a model of real shutter: the rotary wheel.

A wheel rotates at a 3 m/s speed at the rim level, that provides a therotical travel time of 12ms on a 24×36 frame.

A 3mm slit on the rim simulates a 1/1000s speed
