What measurement precision does the Atomfair DLS 836 provide for diffraction light intensity point-by-point measurements?
The horizontal movement measuring stand offers a measurement accuracy of 0.01 mm, enabling precise positioning for point-by-point diffraction intensity scans. Combined with the high-performance photocell detector, the system delivers stable and accurate readings across the optical rail.
Which diffraction structures can be analyzed with the Atomfair DLS 836 system?
The system supports Fraunhofer diffraction from single-slit, multi-slit (2, 3, 4, and 5 slits via the included multi-slit plate), and circular aperture configurations. A multi-hole plate (chromium plate) is also provided for circular aperture experiments.
What are the key infrastructure requirements for setting up the Atomfair DLS 836 optical rail?
The optical rail is 1.2 m long, made of hard aluminum with a profile width of 20 mm and straightness tolerance of 2 mm. Three types of sliding bases (ordinary, horizontal adjustment, and 2D adjustment) are included to facilitate precise alignment of optical components along the rail.
The Atomfair DLS 836 is a complete optical rail system for undergraduate physics labs, integrating a 1.5mW He-Ne laser, precision translation stage, and multi-slit/circular aperture plates to enable point-by-point Fraunhofer diffraction intensity mapping. Its 0.01mm measurement accuracy and manual curve-plotting workflow support quantitative analysis, though the system requires a dark environment and manual data acquisition.
Positive
- High-precision translation stage: The horizontal movement measuring stand provides 0.01mm measurement accuracy, enabling precise point-by-point mapping of diffraction intensity distributions for quantitative analysis.
- Comprehensive accessory set: Includes a 1.5mW He-Ne laser, multiple slit plates (2-5 slits), circular aperture, and two lenses (f'=6.2mm and 150mm), supporting diverse diffraction experiments without additional purchases.
Trade-offs
- Manual data acquisition required: The system requires manual point-by-point measurement and hand-drawn intensity distribution curves, which is time-consuming and limits throughput for large datasets.
- Environmental sensitivity to vibration and light: The 1.2m optical rail and sensitive photocell demand a stable, dark environment; ambient light or mechanical vibration can compromise measurement accuracy.
