support for OPTIC-2 or OPTIC-3
The OPTIC-2 and OPTIC-3 are out of service and we do not have parts any more more these units. So broken instruments cannot be repaired, sorry.
The liners, ferrules and o-rings are still the same as for the OPTIC-4 and can be used without any problem.
(the last OPTIC-3 was sold in the year 2011 and the unit is out of service since 2018)
