Includes five distinct diffraction elements: 1\/2\" single slit, 1\" double slit, 1\" round hole, 1\/2\" mesh, and a composite multi-shape grid, all sized 50x50mm for seamless experiment setups. 2. Composite grid integrates a selection of geometric openings and linesa circular hole (0.36mm diameter), triangle (0.3mm sides), square (0.2mm sides), rectangle (0.6mm x 0.28mm), and denser line zones at 30 and 60 lines\/mmto support complex interference demonstrations. 3. Designed for optical physics exploration, this set allows observation of classic interference and diffraction phenomena using lasers, LEDs, or white light, perfect for classroom demonstrations and individual study. 4. Calibrated slit widths and spacings let users compare the influence of single, double, and multiple slits, and examine how different line densities (20\/40\/60 lines\/mm) shape fringe patterns and spectral effects. 5. Lightweight plastic construction makes each grid easy to handle and store, portability and suitability for use with most optical mounts or slide holders; check sizing for compatibility before use.
