New port nrc 900 three-axis spatial filter
NEWPORT NRC 900 THREE-AXIS SPATIAL FILTER
This spatial filter is an elegantly simple device featuring an accessible design with precision micrometer control over pinhole placement and objective lens focus. The pinhole mount is magnetically registered against the machined faces of the non-rotating X-Y adjustment spindles. A precision-machined slot in the pinhole mount mates repeatably to the spindle face, resisting accidental motion of the mount while permitting fine adjustment. The objective lens Z-axis motion is provided by a precision linear bearing, so that focus is found and maintained without jitter or side-play. The long-travel focus adjustment accommodates virtually any objective lens. The open architecture of this spatial filter makes it especially easy to change pinholes and objectives.
These spatial filters are designed to accommodate all M-Series Objective Lenses, the L-4X and L-50X Infinity-Corrected Objective Lenses, and 900PH-Series Mounted Pinholes.
