Zeiss Ikon High Frequency Camera ZL-1 - 35 mm - is a new design based on the
approved principles embodied by the Wise ikon high speed motion camera which
has been used with best success for more than two decades, but also incorporates
the experience gathered during ',this period. It is a standard film cine camera
for extremely high frame speeds, used for the investigation of very rapid
movements. While the ordinary frame speed for exposure and screening amounts
to 24 frames per second, the frame speed of the High Frequency Camera ZL-1
can be increased to more than sixty times this value, the film tra?:elling at
a speed of more than 60 miles per hour through the camera. If the film
is screened at the ordinary frame speed, the time scale is correspondingly
magnified. So to speaL, the time is visualized through a magnifying glass.
Of course it is not possible at these high speeds to run the film intermittently,
Indeed it `ravels continuously,' and the rays emanating from the object, are
projected upon it over revolving mirrors, forming a stationary picture on the film.
The highest speed of frames amounts to 1500 per second for the size of
18 x 24 a1.:, and 3000 per second for size 9 x 24 mm. Frequencies of 250, 500, 750
and 1000 frames per second can moreover be attained by exchanges b le driving
wheels, while a hand crank is provided for low frequencies of up to 100 frames
per second.
The drive is by a 220/380 V 30 Cycles three-phase a c motor.
The film transport is actuated'over an electro-magnetic coupling.
