This kit features two 8 x 10 cm slides: the slitfilm slide contains 21 different slit patterns featuring a range of slit widths, spacing and multiples for generating different diffraction patterns; the other has five bands of progressively narrower and denser slit patterns for testing the limits of resolution. -- Each film is mounted in a glass sandwich to protect it from scratches.
