Micro-lithographed discs with a diameter of 40 mm for diffraction or interference studies. 2 sizes of slits for single-slit chips: - Width 50 µm (ref 204 108) - Width 100 µm (ref 204 109) With these chips, evaluating students during the lab session is very quick. The teacher already knows on which slit width the student is working. These chips can be used with a point or extended laser beam. Using them with white light will require filtering the signal to maintain a good signal-to-noise ratio.
