Our 910A Series 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. Together, these adjustments provide all the flexibility needed to easily orient the spatial filter for optimum performance.
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 pinholes must be selected and purchased separately (see the Lens/Pinhole Selection Guide). These spatial filters are designed to accommodate all M-, MV-, and L-Series Objective Lenses (see Objective Lenses), and 910PH-Series Mounted Pinholes (see High-Energy Pinhole Apertures).
