A slit that allows two precise blades (sharp blades) to face each other and vary the clearance between the blades.
It is used for spectroscopic devices, schlieren optical systems, diffraction experiments, etc.
With spectrophotometers and schlieren optics, you can fine-tune the slit width to find the best conditions for light and resolution.
Smooth movement in the order of tens of micrometers has been achieved while maintaining the degree of parallelism of the two blades by the precise movement mechanism.
There is the PSL-0, which is used for ultraviolet, visible and infrared rays, and the SLX-1, which uses tantalum blades that do not transmit X-rays.
With the PSL-0, the left and right blades move simultaneously, and the slit width can be changed without changing the center position of the slit.
The SLX-1's left, right, and top and bottom blades move independently, allowing you to change the position and rectangular shape of the slits.
The PSL-0 can adjust the slit length by sliding the slit length variable plate.
A micrometer head type (PSL-2) with a slit width of 10 μm or less is also available.
* Using a high-power laser or a pulsed laser with concentrated light may cause holes in the blade.
* Lower the output of the laser or widen the beam.
