All about the product:

Description

These slits, which can be used with the Lhires III or LISA, have two widths: a narrow part for full instrument resolution, and a wide part to ensure that all the star’s light is collected. By combining observations of the same star with these two slits, you can perform spectro-photometry, i.e. obtain not only the star’s spectrum, but also its total luminosity (photometry).

Four positions available:

  • 23/200µm
  • 27/250µm
  • 31/300µm
  • 35/350µm
