Adjustable Slits / PSL_SLX
Adjustable slits have two razor sharp opposing blades that can be adjusted to vary the air gap between them. Typical uses include spectrophotometers, Schlieren optical systems and diffraction experiments.
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.
