Product Overview
The Michelson Interferometer (Complete with Sodium Lamp Assembly) is a sophisticated optical instrument designed for precise interference pattern analysis and wavelength measurements. Engineered with high-quality optical-grade glass mirrors and a durable aluminum frame, this interferometer ensures minimal vibration and maximum stability during experiments. The integrated sodium lamp provides a monochromatic light source (589.3 nm), eliminating the need for external illumination and simplifying setup. The beam splitter, coated for optimal reflectivity, divides the light into two perpendicular beams, which recombine to produce interference fringes for detailed study. Adjustable mirrors with fine-tuning screws allow for precise alignment, enabling accurate measurements of optical path differences and refractive indices. The compact yet robust design makes it suitable for both educational demonstrations and advanced research applications where reliability and precision are critical. The interferometer’s modular construction facilitates easy maintenance and component replacement, ensuring long-term usability in laboratory settings.
FAQs
1. What is the wavelength of the sodium lamp included in this interferometer?
The sodium lamp emits light at a characteristic wavelength of 589.3 nm, which is ideal for creating clear interference patterns in optical experiments.
2. Can this interferometer be used to measure the refractive index of transparent materials?
Yes, by introducing a thin film or transparent sample into one of the optical paths, you can observe fringe shifts and calculate the refractive index based on the interference pattern changes.
3. Is this interferometer compatible with laser light sources instead of the sodium lamp?
While designed for the included sodium lamp, the interferometer can accommodate other monochromatic light sources like lasers, provided they are properly aligned and have compatible wavelengths.
4. How should I store the Michelson interferometer when not in use?
Store the interferometer in a dry, dust-free environment with the mirrors covered to prevent contamination. Avoid exposure to direct sunlight or temperature fluctuations to maintain optical alignment.
5. What alternatives exist if I need higher precision than this model offers?
For ultra-high precision applications, consider interferometers with piezoelectric actuators for mirror adjustment or models equipped with helium-neon lasers for improved coherence length and stability.
