K2.0006526 SMB-1 Adapter for SMB-2 Filter Stages

A step-down adapter that permits SMB-2 4 inch x 5.65 inch filter stages to be mounted to the 6.6 inchx 6.6” SMB-1, without affecting wide-angle coverage. The adapter also allows SMB-2 filter stages to be mounted to the back of a stack of SMB-1 filter stages. If needed, SMB-2 filter stages (1-stage K2.0002143, 2-stage K2.0002144) and SMB-2 back plate adapter (K2.0007765) can be ordered separately.
