Will it chop frozen grapes?

I just tried. This is ineffective against frozen grapes.

What is the difference between the various options?

Basically the line spacing. We offer 500 ln/mm, 1000 ln/mm and cross axis 13,500 line/ in. The 1000 ln/mm spreads the spectrum the most.

Your scale is backwards. Red is the longer wavelength.

I think they meant the scale to be applied to the rainbow colors of the plastic part itself (just as a side reference relating color and wavelength), since the positions of colors on the grating depends on angles etc., they aren't tied to a specific position on the grating anyway.
