Description

The laser beam is aligned with the photocell in the black aluminum cylinder, which is connected to a timer with large display. The camera is mounted on an optical post with the standard camera thread on one end, and positioned so that the laser beam will reach the photocell when the shutter is open. Reset the counter and cock the camera, and timer will measure the shutter opening time when the "picture is taken." Bring your own camera or have students bring theirs to check the calibration of the shutter speed.
