Copal is a Japanese company making camera shutters.
The Copal leaf shutters are used on many rangefinder, TLR and view cameras. They are high quality shutters which tend to cost less than Compur shutters.
There are several variations of the shutter. Some use a simple inertia gear set to regulate speed. Other Copal shutters, such as the widely used MX, obtain a wider range of speeds by using a typical escapement, but have the same basic design.
Copal also made focal plane shutter units, for the Japanese SLRs. The best known model was the Copal Square vertical travel metal curtain shutter.
