625-RC Series Mirror Mounts are rod-mountable devices that provide vertical positioning flexibility and convenience for large diameter mirrors. They are compatible with Newport's rod models 40 , 41 , 42 , and 45 as well as the new SR-series Magnetic Base Optical Support Rods and incorporate the same stable kinematic design as our 600A Series Heavy-Duty Configurable Optical Mounts, with hardened kinematic contacts at all three support points. The standard versions are configured with 100-TPI precision AJS-series Adjustment Screws. Where a direct reading is desired, SM Micrometer versions are available simply by appending -M to the part number.
