Question: Preferred slit size?

We currently sell this pack: https://publiclab.myshopify.com/collections/spectrometry/products/acetate-slit-bundle

With 0.09mm, 0.12mm. 0.15mm, and 0.18mm slits. But we're not sure the exact reasoning behind these sizes except that they're 0.03mm apart. Would people like different sizes? Would people be upset if we simplified and started making only 0.1 and 0.2mm slits?

What do you use these for and why?

Some good notes on this over the years:

And the original post on slits here: https://publiclab.org/notes/mathew/09-25-2013/photo-printed-collimation-slit-for-the-backpack-spectrometer -- @mathew writes:

In the balance between accurate spectra and light sensitivity, the .09mm slit seems to be the best. Its spectral peaks were just as pointy and clear as at .03mm but it produced brighter spectra, without the cutoff and internal reflections that began to be an issue at .12mm.
