Shelyak Slits 19um- 50um -75um -100um

This is a Set of Wide Slits for LISA or Lhires III spectroscopes.  They are to be combined with a Slit Holder for LISA or Lhires III.

There is a 19 micron hole to help you with the finest adjustment of your spectrograph, and three additional slits with 50, 75, and 100 micron hole widths, respectfully, for larger adjustments.

The slit choice is made by rotating the squared slit holder.
