◦A precision positioning mechanism keeps the blades straight and parallel with minimum incremental motion on the order of tens of microns.
◦Two types are available. The PSL-0 is intended for ultraviolet, visible and infrared radiation. The SLX-1 is intended for use with X-rays and has tantalum blades to efficiently block X-rays.
◦The PSL-0 moves the blades left and right simultaneously, enabling adjustment of slit width without changing the center position of the slit.
◦The SLX-1 moves the blades independently, left and right, or up and down, thus enabling change of slit position and rectangular shape. The slit length on the PSL-0 is adjusted by sliding the adjustment plate.
