Optical setup: proper lenses selection

Dear all,

I am going to realize an experimental optical setup and I need your suggestions to make the correct selection of lenses.

A polychromatic light beam coming from a monochromator (400-700, slit dimension: 1 mm)

has to be focused onto the base of a cylindrical lens (acting as a prism).

I need the light beam striking onto the glass prism being almost parallel through the path along the prism.

I think that a convergent beam with a section of 2 mm can “simulate” this ideal situation.

Can you suggest me a combination of lenses able to direct the light beam from the monochromator to the prism?

 

Thank you in advance
