Abstract
Several improvements to Omega negative carrier assemblys baffle the optical light path against light leaks. These improvements collectively gather together to form a system that continually assures the alignment of the condenser assembly and its lifting apparatus. This system will allow serviceable alignment of the lifting apparatus when necessary. This negative carrier assembly will be completely manufactured by computerized machine tool methods.
