Product Description
As per the Newport website:
The 910A Compact Five Axis Spatial Filter has a space-efficient design combining five-axis alignment with high stability for set-and-forget adjustment. Precise XY translation of the pinhole plus true gimbaling of the entire assembly are achieved with precision 100 TPI screws with new knobs including an integral hex hole, providing smooth, high-resolution motion. Our new zero-freeplay XY mechanism ensures accurate positioning and enhanced long-term stability. Translation along the optical Z-axis is accomplished without rotation of the pinhole by a knurled ring with a precision 80 TPI thread. New independent locks for each axis of translation and rotation securely lock the mechanism, not just the actuator screws, maintaining stable alignment. Engaging or disengaging each lock has negligible influence on the other axes. Mounted pinholes simply thread into the body of the spatial filter. RMS-threaded objective lenses attach to the lens holder, which is then clamped to the positioner. The lens holder has an integral iris diaphragm to aid in coarse alignment of the beam to the spatial filter and for blocking out stray light. Objective lenses and purchased separately. This spatial filter accommodates M-, MV-, and L-Series Objective Lenses, and 910PH-Series Mounted Pinholes. For maximum stability when mounting directly to an optical table, these spatial filters are supplied with a slotted base plate that can be attached to either side of the unit. The spatial filter can also be post mounted, using either the 8-32 or M4 threaded hole in the bottom.
