In the 1960s the company began producing the well-known Copal Square vertically travelling metal blade focal plane shutter, which was very successful and was used in cameras by many prominent manufacturers.

It works over a wide temperature range.[5] The electronically controlled Copal Square E (1968) was used in the Yashica TL Electro X, the Canon EF, the Nikkormat EL. For Minolta XE and the Leica R3 the Copal-Leitz Shutter CLS was developed in 1972. For the professional Nikon F4 built 1988 until 1996 the Copal Square was developed and reached 1/8000 s and 1/250 s with flash.[4]
