Can be attached to the ends of the large optical rails (OBA-L/LH) to provide ±8mm height-adjustment capability.
• OBL-LS has one foot and the OBL-LW has two feet. One OBL-LS and one OBL-LW should be used on one large optical rail. Flatness adjustment is easier with three 3 axes versus 4 axes.
• Please use the CAA-25LS if you use it with OBA-SH.
