Diffraction Gratings Slide – 100, 300 & 600 Lines/mm

This Diffraction Gratings Slide features three high‑quality gratings mounted on a single, durable slide, making it ideal for exploring diffraction, interference, and the wave nature of light in school and college physics lessons. Each grating provides a different line density—100, 300, and 600 lines per millimetre—allowing students to compare diffraction patterns and analyse light at varying resolutions.

The slide includes three 16 × 9mm apertures, each containing a precision‑ruled grating for clear, accurate optical experiments. With overall slide dimensions of 90 × 30mm, it fits easily into standard optical benches, ray boxes, and spectrometer setups.
